Can I return to China to live after immigrating to Australia? How many years to live? Or do you want to go back to China to do business and start a company after emigration?

At present, it is stipulated that you can renew your PR status if you stay for two years within five years, so you can stay in China for three years within five years, or you can live in China for four years within five years, and then you can be naturalized, so you can live in China with a visa from China, but it is more troublesome, especially if you want to do business. Unless your family relationship is hard.
