the most popular amusement park is roller coaster. The roller coaster starts from the balcony on the 2 floor, and the metal car goes down the plastic track. The track has cement pile, very firm. In order to increase the safety performance, grandpa also provided a seat belt to the carriage. Grandpa said that this track can bear the weight of an adult, which is fine for his 2 year old granddaughter.
the old man made a club for a friend when he was young, and had 20 years of experience in electricians. He said, "if I see anything or think of anything, I will create it." With such a spirit of hard work, the grandchildren's amusement park will be more and more lively! (internship compile: Wang Yanni reviewer: Zhu Yingku)
