In normal times, Mingyueyuan is a window of awakening. Legends look at the endless scenery outside the window all year round. It feels like a flat, but in the purple sun flower season, the courtyard is full of flowers of various colors. It is like a paradise for flowers. To watch the purple sun flower is recommended to go on weekdays and cloudy days, there will be a lot of people on rest days (although there are many working days).
