The air here is really fresh, high negative oxygen ion, PM2.5 ultra-low! The humidity is suitable. It's really comfortable here. It's suitable for summer. If the water comes in July, it should be better. The annual ticket is 160 adults. Every weekend I feel itchy to drive from Shenyang to inhale oxygen! I heard that October 4th is the most beautiful time for maple leaves. It will come again from one week to half a month.
