Zhou Dasheng and Leofoo are domestic brands.
There are only differences in technology, style and after-sales service.
Zhou Dasheng wants to shine on Chow Tai Fook and Zhou Shengsheng. His name is close to theirs, but he is not related by blood. The quality of things is far less than Chow Tai Fook and Shengsheng.
Therefore, Chow Tai Fook is the best choice.
