Where can I find workers who have been doing external walls for a long time?

You can find a fish net. You can download a fish bubble net directly, and click on it to search for external wall workers. But all workers have a process of adaptation and running in. If there is no pleasant running-in during this period, your cooperation may be this time, so it is mainly to see whether the employers and employees get along well, so we can talk about whether you can follow you for a long time.
