Rong represents prosperity, so it can be named as Rong Xin (XXX) Co., Ltd. Rong Xin sounds good but not good-looking, so it is changed to Rong Xin to look good, for example.
Rongxin Shoes Co., Ltd., Rongxin Hardware Accessories Factory, Rongxin Clothing Factory, etc. I hope it will be useful to you.
