In 2003, Ye Youcai, the former Guangzhou Garrison, was appointed as the Deputy Chief of Staff of the Garrison. The concept of national defense has weakened. Chen Yuanhua, deputy commander of Guangzhou Garrison, pointed out that after years of not fighting, many people's national defense concepts have become weak, and in recent years, there has been a phenomenon of deliberately evading military service. For example, the night before the urine test, someone went to karaoke all night and drank beer, which led to the failure of the urine test the next day. Ye Youcai, deputy chief of staff of the garrison, also said that some people now regard being a soldier as a burden, as something that they can go or not. So some people pretend to be sick during optometry, and some people pretend not to see it on purpose.
