　　The government of China looks after the memorial very well．In 1986, the government spent 1.2 million RMB．They repaired the roofs and walls of the buildings．About 8 million people come to visit the memorial every year．For many years, it was free．But since 1992, you must pay an entrance fee of five RMB．All the money is used to help with the repairs and cleaning work．
