Guangxi Science and Technology Museum, which used to be a place I often visited on weekends, is a paradise for children. When they come, they don't want to go. It integrates knowledge and interest. There are many free tickets. I don't need to buy tickets. An adult can bring two children. At that time, I took my nieces and nephews with me. They spent a whole day together and were very happy. Today, I am accompanying my mother to go shopping. Many changes have been made. Now, all of them are specialized exports. In the past, the entrance and the exit were together. It was crowded and improved.
