What font is used to write the preview of the first episode of the TV series Romance of the Three Kingdoms?

Romance of the Three Kingdoms began in the late Eastern Han Dynasty, and it was definitely written in official script, with a sense of "Cao Quanbei" in style.

Since the mid-Western Han Dynasty, an independent official script form without seal script (including structure and strokes) has been completely formed. Typical examples are the inscriptions on lacquer boards unearthed from the Han tombs in Le Lang in the first year of Xuandi Wufeng in the Western Han Dynasty (the first 57 years), Chengdi Heping (the first 28 years), Tianfeng, the first year of the founding of the People's Republic of China (14 years), the fourth year of Pingdi in the Western Han Dynasty (4 years) and the twelfth year of Yongping in the Eastern Han Dynasty (69 years).

Similar glyphs can also be seen in many inscriptions in the Eastern Han Dynasty. The most famous monuments are Huashan Temple Monument in the eighth year of Yan Xi (165), Shi Chenbei Monument in the second year of Jianning (169), Cao Quanbei Monument in the second year of Zhong Ping (185) and Huashan Temple Monument in the third year (186).
