After the epidemic, Jiaotong University is more convenient to enter from the gate of Huaihai West Road on Panyu Road. The gate of Huashan Road has been locked for a long time. It is still very rewarding to visit the old library near the gate of Huashan Road. The building is very old and there are successful people who have made outstanding contributions to the country. Taxi! It is still necessary for the children to visit!
