I have to make an appointment for the weekend before I go. I went there on Friday, but a group of bear children felt particularly suitable for primary and secondary school students. What impressed me most was that the miniature version of the robot world pet cat, Dujiangyan, was so cute and lifelike. After reading it, I felt like going to Dujiangyan Bar, at least the principle of Dujiangyan Bar was clear. Drainage 28, sand drainage and the 4D exhibition hall of the origin of life are great.
