What is the name of this building in Yuanmingyuan, Beijing?

Flower array: maze, has been rebuilt. The gate of Huanghua Garden is bell-shaped with two gates carved in brass. In the center of the garden maze is a stone pavilion with western-style seats. Every Mid-Autumn Festival, the emperor sits in the pavilion, and the ladies-in-waiting enter the maze entrance with Huang Lian lanterns. Whoever gets to the pavilion first will get a reward, so it is also called Yellow Flower Array.
