What is Yan calligraphy?
Yan, like Qin, has been in a corner for a long time, living in the north, with little traffic with the countries in the Central Plains. There are few inscriptions on the sacrificial vessels of the State of Yan, and the word "Yan" in the inscriptions is generally written as "Pin", such as "Gong Pin Zha" and "Pin Hou Slaughters Ghosts". The inscriptions on the weapons of Yan State are very distinctive. The inscriptions are carved, mainly rigid and short, with square structure and small triangle structure, creating a stable and ethereal internal space.
