1. Gu Guoqiang studied under Mr. Ding Yaping, Lv Yaochen, Li Changhong, Cao Wanfen and other purple sand masters. After decades of experience in making pots, he is particularly good at wringing and burying mud. The teapots made are all made of raw purple clay without any chemical pigments. They are handmade, with good materials and good quality.

2. Using raw ore purple sand, there are few craftsmen who make pots by hand, let alone high-quality purple sand pots, so Gu Guoqiang's purple sand pots have high collection value.
