1. Style: The jade sold by Yu Meiren Feifei has been professionally designed and processed, which is deeply loved by consumers, while the jade style of Lao Zheng's family is old but not new.

2. Quality: every product of Feifei has a special quality certificate, and its reputation is guaranteed. However, Lao Zheng's jade is a niche brand and does not provide certificates, so Feifei's jade is good.
