Risk of construction engineer's failure to cooperate with social security

Do you want to ask whether it is risky for builders not to cooperate with social security? Big, according to the China French Open query. The construction engineer can only do "short-term temporary employment", without the cooperation of social security, which is costly and risky, and also causes the risk of frequent registration. 500,000 first-class construction engineer certificates have been abandoned, mainly for national staff and those who have formal jobs and cannot transfer to social security. So it's risky.
