Introduction to Yiye Hall: Yiye Hall is located in the northwest of Guyi Garden. It was built in the Ming Dynasty and is an old district of Yiyuan. With Yiye Hall as the center, there are winding corridors and Youshang Pavilion in the north, and Yuanyuexuan, Xiaosonggang and South Hall in the south. Yiye Hall is surrounded by ancient buildings such as Wulaofeng, Gupanhuai, Xiaoyundou and Osmanthus Forest. Yiye Hall was originally the main hall in the garden, where the owner entertained guests and rested. Because it had nanmu as pillars, it was also called the "Nanmu Hall". And because roads are connected on all sides, you can have a panoramic view of the entire garden from the hall, so it is commonly known as the "Four Side Hall".
