Who knows the profile of Li Tinggui?

Li Tinggui is the owner and inventor of Huimo, the treasure of ink in Four Treasures of the Study. A brief introduction about Li Tinggui is as follows:

Huimo began in the Southern Tang Dynasty. The founder was Chao He Ting Gui, and Li Yu, the queen of the Southern Tang Dynasty, loved painting and calligraphy, so she called Ting Gui the official of ink affairs and gave her the country name. So the surname became Li, and Li Tinggui became a master of ancient and modern Mohism. During Song Xuanhe's reign, there was a situation that "gold is easy to get, but Li Mo is hard to find". In the year of Song San (A.D. 1 12 1), the famous ink such as Hui ink and Li Mo was changed and unified into Hui ink. A good Huizhou ink is "rich in muscle and greasy, glossy as paint", with the characteristics of light touch, clear grinding, fragrance, firmness as jade, silent research, a bit like paint, and timeless. It is said that Dong Qichang, a great scholar and calligrapher in the Ming Dynasty, was full of praise for the ink made by Cheng Junfang, a master of Huizhou ink making at that time, such as "Xuanyuan Reiki" and "Liao Tianyi": "After a hundred years, there is no monarch room, but there is the ink of the monarch room; After a thousand years, there is no ink in the monarch room, but there is the name of the monarch room.
