For example, the famous sociologist Fei Xiaotong wrote his undergraduate thesis "Research on Wedding Customs" in 1933. He sorted out and analyzed the marriage customs in the local chronicles of 207 places in China at that time, and spent about two years writing a paper, which still has great reference value.
However, according to a survey conducted by Labor on 20 14, more than 90% of undergraduates finished their graduation thesis in less than 30 days, and 47% of them even spent less than 10 days [1].
