Oct. 28 was the ninth day of the ninth month in the Chinese calendar, the Double Ninth Festival. Chenshan Botanical Garden's annual parent-child activity "Happy Tour, Happy Harvest" was held as scheduled. Before the activity started, 100 picking tickets were distributed.

This activity was carried out in the form of a garden tour. According to the currently ripe vegetables and fruits in the garden, three spots were set. The fruits and vegetables to pick were the grapefruits close to the children's park, the snake gourds and mouse gourds close to Bridge No. 3, and the sunflowers close to the botanical garden for blind people. Visitors with the picking tickets could go to these places to enjoy the fun of picking and harvesting fruits with the help of the staff.
