It lies in: brand effect (just like the brand effect of clothing, well-known brands are expensive), style (novel), workmanship (fine) and color (pure, generally speaking, not bad).

Famous brands are certainly good, but if the money is not too much, I think ordinary brands are ok, and the price difference is much lower. Chow Tai Fook's current rate is about 2 10 yuan, while others are between 170- 190 yuan. If you like, it should be cheap and good. Moreover, if you don't want it and want to sell it, the price is similar to that of Chow Tai Fook Dongdong.
