Is it deceptive to recruit laborers in Dongguan, Shenzhen? Fraud? How was work, Gai Lou?

Sometimes some people cheat people, but most of them are true, because the construction site is too tired, and the work on the construction site is worse than the coolies on the dock (there must be strength) (both are coolies, and the labor intensity on the construction site is lower than that on the dock, but sometimes the life on the construction site is in danger). This is not something that ordinary people can do, and there is a shortage of people everywhere on the construction site. It may be deceptive to go to the recruitment office instead of going directly to the construction site. Generally, people are recruited on the construction site directly through the intermediary, or there are recruitment notices outside the construction site. Go when you see it, and you'd better not believe those small advertisements posted everywhere outside.
