Take the No. 4 bus at Xinmi bus stop and then go through an alley. The place is quite biased. Mixian County Ya was built in the Sui Dynasty, AD 616. It has a history of more than 1400 years. After entering the door, there is a lotus pond, which is also the only county magistrate with lotus pond in the country. Another feature is the secret passage inside. More than 500 metres have been repaired, and the secret passages are like labyrinths, extending in all directions. There are also prisons that have been in use until 2003, which is also a miracle. County Ya has five entries, gate, Yimen, Jieshifang, lobby, two halls, three halls, Daxianlou are well preserved. In short, Mixian County Ya is worth visiting.
