What brand of calligraphy brush is better?

Huzhou Wang Yipin Bizhuang's "Tianguan" brand lake pens, especially Yang Hao's, are of good quality. The wolf brush in Zhouhucheng, Shanghai is quite good.

Mo Ding in Shanghai and Mo Ding in Anhui, such as Hu Kaiwen, Cao Sugong and Li Tinggui, are all good. Generally speaking, certain parts of meticulous painting can be used in Song Yanmo. In most cases, oil smoke ink is used in calligraphy and painting works. When buying Mo Ding, pay attention to the words "lampblack 10 1" printed by regular manufacturers and Mo Ding.
