There are many factories in Guangzhou. If you learn computer and master a few softwares, you will have a great advantage in entering the company.
Next time, if you have enough time, you can also consider doing some online business and opening a shop, because Guangzhou is also a logistics center, near the sea.
Everything inland is much cheaper.
There are still many opportunities. As long as you have a good grasp, you can still do your own thing, not afraid of hardship and fatigue.
