What is the origin of the name Chunhua Xuan?

Chunhua Xuan is the main building of Changchun Garden Center, which was built at 1745. It was built by Qianlong to support his life after returning to politics. Chunhua Xuan is located in the Hanjing Hall in the center of Changchun Garden. When it was completed, it coincided with the completion of the "Re-carved Spring Pavilion Sticker", so it was embedded in the left and right cloister walls, hence the name Chunhua Xuan.
