The environment is super good and super clean. Because it's hot and lazy and needs an umbrella, there is no extra hand to take pictures. There are also suggestions for several people to go together. On the edge of that Japanese courtyard, a black man stopped me to ask for money, pointed to his ears, pointed to his mouth, and showed me a piece of rotten paper, which meant that the deaf and mute asked for money. I ignored him and went on. Later it was estimated that he was watching me because I went there myself. In a small place, I found him coming face to face with me. I immediately changed my way, but it was too late. He called me loudly and loudly. Finally, I had no choice but to give him two yuan and hurry away, for fear that his companions would come back to me for money. It is true that several waves of beggars were seen in the park.
