Introduction to Hanhui Tower: Hanhui Tower is one of the three famous buildings in Huangzhou. It was built in the early Northern Song Dynasty. Because the building is close to the mountain and faces the river, it is exposed to the afterglow of the setting sun in the evening, and the bright moon shines brightly at night, so it is named. The current building was renovated in 1982 and is also known as the Dongpo Exhibition Hall. It displays Su Dongpo's works, stationery and later generations' works on Su Dongpo.
