Use yellow and cyan as the background. There are white clouds in the sky. There is a mailbox on the cyan grass with the words "Time Post Office" written on it.，A lot of letters flew out of it. Some of the letters flew out and were opened.，There are many graduation photos, graduation speeches, etc. There are a few road signs and traffic lights not far away. The road signs read "Junior High School One", "Junior High School Two", "Junior High School Three", "Science", "Liberal Arts and Commerce".
