The five baht money in this period is collectively called "five baht in six dynasties" in the coin world. The Six Dynasties were Wu, Eastern Jin, Southern Song, Qi, Liang and Chen. The five baht money in this period was badly cast, and the Cultural Revolution rate and strokes were incomplete. Some people write "five baht" as "hardware", while others write "five baht" as an anti-text. However, there are exceptions to the five baht, such as "Taihe Five baht" and "Yong 'an Five baht" in the Northern Wei Dynasty, which are called "as important as their prose" in history, and their high quality not only reminds people of a series of successful reforms of Emperor Xiaowen in the Northern Wei Dynasty.
