2017，I joined the "Chinese Truck Driver bet365 bonus code 2023 bet365 bonus code 2023 Group"，Looking back on five years of bet365 bonus code 2023，Persisting in longitudinal bet365 bonus code 2023 and immersive investigation is the most valuable bet365 bonus code 2023 experience，It is also the most important path to “seeking knowledge from reality” as expected by Mr. Fei Xiaotong。

　　Longitudinal bet365 bonus code 2023: the “emergence” of bet365 bonus code 2023 topics and the possibility of comparison

Longitudinal bet365 bonus code 2023 is a classic bet365 bonus code 2023 method with a long history，Meaning to record the status and changes of the bet365 bonus code 2023 object at different points in time within a long period，To effectively reveal the process、Heterogeneity and Causality。Classic longitudinal studies usually use quantitative methods，But since 2000，More and more studies are innovatively adopting qualitative techniques to collect and analyze longitudinal data。The truck driver study also adopted a longitudinal qualitative approach，To explore the labor process of truck drivers and its intersectional results with related factors。

Based on our bet365 bonus code 2023，The classification of qualitative bet365 bonus code 2023 and the division of quantitative bet365 bonus code 2023 theorists tend to be consistent，Can be divided into tracking bet365 bonus code 2023 and trend bet365 bonus code 2023。Following studies are repeated observations of the same sample，Many truck drivers and truck drivers were interviewed by us multiple times during the bet365 bonus code 2023 period。Trend bet365 bonus code 2023 emphasizes sampling different samples from the same population in different periods for testing，Our bet365 bonus code 2023 also happens to use “transmission samples” as the sample pool，Select different bet365 bonus code 2023 subjects from the same sample pool every year for participant observation and in-depth interviews。

When collecting longitudinal data，We consciously balance continuity and fluidity。Take my bet365 bonus code 2023 as an example，Whether conducting tracking bet365 bonus code 2023 or trend bet365 bonus code 2023，My interview outlines are composed of fixed questions and changing questions based on theoretical concerns: the fixed questions include the demographic sociological characteristics of the interviewees、Labor process、Marriage and family、Social interaction、Gender concept、New media adaptation and future prospects，The issue of change is specifically extended according to different bet365 bonus code 2023 topics: the study of truck drivers focuses on the gender division of labor among truck driver couples，bet365 bonus code 2023 on female truck drivers focuses on occupational gender segregation，Volunteer bet365 bonus code 2023 focuses on the interaction between career and volunteer motivation，Cross-border transportation bet365 bonus code 2023 focuses on the comparison between cross-border transportation and domestic transportation。

The benefits of longitudinal bet365 bonus code 2023 are obvious。The most prominent thing is the continuous “emergence” of bet365 bonus code 2023 topics closely connected with field sites。The first way of “emergence” is the “emergence” of cross-analysis factors，It has two dimensions: one is the discovery of clear cross-cutting issues at the empirical level，For example, the intersection of labor and gender began with my confusion about “couple cars” when I was studying the labor process，The intersection of labor practice and volunteer service comes from the perception of the bottom social status that truck drivers repeatedly emphasize。Another dimension is to discover the possibility of deepening explanations at the theoretical level。Theoretical explanation about the labor role of Kasao，I started as a "production helper and housewife"，To "Indispensable workers in the road freight industry"，Using the changes in gender concepts to explain the tension between the objective labor role of "card" and the subjective gender role of "sister-in-law"，Deeply feel the space for theoretical progress brought by longitudinal bet365 bonus code 2023。

The second way of "emergence" is reflected in the new topics brought about by the flowing life history of bet365 bonus code 2023 objects。The bet365 bonus code 2023 topic of volunteer service was brought to me by a truck driver friend who became an anti-epidemic transportation volunteer，The bet365 bonus code 2023 on cross-border transportation originated from curiosity about the Horgos Port during an interview a few years ago，Until recently, the switch from domestic transportation to Laos、There are more and more truck driver friends in Thailand and Myanmar，This topic is naturally put on the bet365 bonus code 2023 agenda。This kind of "emergence" is not only the sole choice of researchers，Also often reflects the reflexive nature of the bet365 bonus code 2023 object，Full display of their distinctive color of initiative。

In addition to the continuous “emergence” of bet365 bonus code 2023 topics，Longitudinal studies also increase the possibility of comparison。The first is the comparison of the individual life histories of the bet365 bonus code 2023 subjects。In five years of bet365 bonus code 2023，We watched the truck drivers move between different models at close range、Supply、Nature of employment、Transportation distance and industry，Accompanying Kasao from following the car to staying behind、From staying behind to following the car，Have also witnessed the growth of many Kavas。The vertical comparison of each microscopic life history constitutes a colorful chapter in the history of road freight transportation in my country。The second is the comparison of bet365 bonus code 2023 data。Although each year’s bet365 bonus code 2023 has a clear theme，But thanks to the continuity of longitudinal bet365 bonus code 2023，We compared many topics。For example, when studying truck wives and female truck drivers，I can access previous interviews with male truck drivers and other employees for comparison，Then summarize a more complete gender concept in the industry。Finally, there is a comparison between the macro-institutional environment and the market environment。Five years of longitudinal bet365 bonus code 2023 gave us the opportunity to experience various changes in macro policies and market demand with truck drivers，For example, the implementation of the "pay per axis" policy，Changes in “drowsy driving” enforcement，Upgrade of environmental protection policy，Updated iteration of car models，The rise and monopoly of online freight platforms，LTL、Large items、Express delivery、Express、Transformation of cold chain and green pass market, etc.，These comparisons form an essential industry background for studying truck drivers，It also provides macro options for causality for us to understand the micro-individual choices of truck drivers。

　　bet365 bonus code 2023 “act” and “knowledge”: the necessity of immersive fieldwork

If the focus of longitudinal bet365 bonus code 2023 is to repeatedly explore the bet365 bonus code 2023 object at different points in time over a long period，Then immersive fieldwork emphasizes the use of all possible means to extensively collect data and conduct in-depth analysis，Always immerse the researcher's body and mind in the field field between "reality" and "knowledge"。

On the one hand，Researchers need to be immersed in intensive fieldwork。Concentrated offline field surveys every year are the main content of bet365 bonus code 2023 driver surveys，But limited by time and place，We need to infinitely extend the rich meaning of the fields within limited time and space。Therefore，In the wholehearted interview、Besides discussions and observations，We always strive to collect all possible information: contact process with contacts and interviewees、Determination of various field investigation matters、The natural environment and customs of the field location、Interviewee’s silence and tears during the interview、The interviewee’s true feelings after turning off the recorder、Interrupted questions and rejected interviews，Especially unusual cases and tacit knowledge required，These need to be understood and recorded in a theoretical sense。

What needs to be pointed out in particular，Participant observation is an integral part of immersive fieldwork，It provides a "sense of presence" that is difficult to achieve in interviews and discussions。2019 study of female bet365 bonus code 2023，I once went to an express company to observe the morning meeting of the driver team。As a woman, I first entered the office、When I see almost all of the people standing or sitting in a small space are male bet365 bonus code 2023，The sense of oppression of occupational gender minorities caused by occupational gender segregation immediately hit our faces。In the same year, I also worked as a part-time loader and followed a city delivery driver to drive a sports car，Every time we arrive at an unloading point, we must quickly unload the order，Then rush to the next unloading point without stopping，The urgency of “catching up the number of trips” made me immediately aware of the differences between different freight divisions of labor。2023，We follow another medium and long-distance trucker to deliver goods，When we set off on the road at 2 o'clock in the morning in total silence，Discover that the road at night is completely a world of trucks: different types of trucks are crowded together、Very lively，The trucks parked neatly in the wide area along the way，Carrying the extremely compressed rest of bet365 bonus code 2023，It also highlights the desolation of individual workers under the endless prosperity。This "sense of presence" transforms the language in interviews and discussions into real voices、Screen and Situation，It is the irreplaceable reality of the field。

On the other hand，Researchers need to immerse themselves in daily fieldwork beyond intensive fieldwork。For me，Everyday fields include three organic components。The first is to carefully organize the interview data，Recreate the "real" scene，And ponder over its true meaning、Formating the theory of "knowledge" through theoretical exploration。I am used to combining data sorting and initial coding，Many theoretical structures and argumentation logic come from this arduous and joyful process of seeking knowledge。The second is to accumulate relevant “new era data”。Except academic works，I also followed 47 companies related to the road freight industry、Logistics Industry、WeChat public account related to the automobile industry and truck drivers，Also downloaded apps from several major online freight platforms and card friend organizations。I pay attention to the information released by these platforms every day，Articles related to bet365 bonus code 2023、Collect and save pictures and videos by categories。These data provide me with broad background information，Allows me to maintain the sense of being “on site” as much as possible。The third is to collect multi-dimensional data defined by scholars as “worker-generated content”，For example, truck driver、WeChat Moments of Card Sisters and Related Practitioners、Douyin、Kuaishou、Card friends organize App posts, etc.。This part of the content shows me the diverse and real work and life of the bet365 bonus code 2023 subjects，It is a necessary supplement to the limited interview data。

What truck driver bet365 bonus code 2023 tells us，Longitudinal bet365 bonus code 2023 can promote the expansion of bet365 bonus code 2023 topics and theoretical comparisons，Immersive fieldwork builds a bridge between experience and theory between "actuality" and "knowledge"，The organic combination of the two can enhance our perception and insight into social phenomena，Discover the unique “constancy” and “social heritage” of Chinese society more effectively。
