Li Changhong and Lv Yaochen are the two masters who have done the best in continuity today, forming their own school. From a technical point of view, Li Changhong's pot is the best. After all, he served as the deputy director, workshop technical director and process chief engineer of Yixing Zisha Factory. To make an inappropriate analogy, Li Changhong is a strength school and Lv Yaochen is an idol school. Few other masters can make pots themselves, so you must recognize this fact when buying pots.
