What knowledge goes into naming commercial stores in ancient China? What are the naming rules?

In ancient China, the naming of commercial stores was very particular. In a word: emphasizing color and seeking good luck.

To be specific: First, how to choose a name that sounds nice. Such as Xing, Long, Mao, Tong, Wang, Shun, Chang, Hao, etc., all names related to doing well, becoming bigger and stronger.

The second is to name the business project according to the five elements. Such names must "generate" their own business. If you are engaged in the carpentry industry, choose a name with water in it, as water produces wood. Or taking the name of Daimu can be helpful. Avoid using names with gold in them, because gold overcomes wood.
