Your Egyptian husband can apply for a dependant visa to stay with you when you are working in China. The copy of your passport, work visa, alien employment license and marriage license are very helpful for his application for dependant visa. You'd better make the marriage license translated by a local notary license, then authenticated by Egypt Foreign Affairs Office and China embassy/consulate in Egypt, then the marriage license can be used in China.

If he finds a work after arriving in China and get all the documents for work visa application, he has to exit China to apply for work visa, then return to China.
