Who can help my father find a job in Zhuhai?

It is not difficult for men in their fifties to find a job. If they have worked in the countryside, it should not be difficult to find a job. Mainly do things like cleaning and sanitation, hotel logistics and so on. These are not difficult and not so tired. Non-manual porters in some companies are also acceptable.

I suggest you also post on websites such as Xiangshan. Zhuhai Window, 58 City, People.com, the effect will be better.
