Introduction to Zhangyan Park: According to historical records, Zhangyan Park can be traced back to the Yuan Dynasty. It was originally a private residence and garden used by Wu Liang, a local prominent family in the Yuan Dynasty. After several generations of management, it was managed by Wu Liang (Zhenshi) in the Ming Dynasty. At that time, it has been expanded into the famous "Wu Family Garden". During the Qianlong reign of the Qing Dynasty, the family fell into decline, and the garden was sold to the Qian family and became part of the Qian Family Yi Zhuang, commonly known as the "Qian Family Garden". During the Republic of China, the Qian family's family declined and the garden was sold to other families, but people still called it the Qian family garden. In the early days of liberation, the garden was desolate and desolate. Since 1953, the park was once named "People's Park". In 1956, the government mobilized the masses to organize and reorganize some scenic spots. In 1958, Zhangyan Park was initially built and opened to the public free of charge in 1960. Wei Wenbo, former secretary of the Shanghai Municipal Committee of the Communist Party of China, inscribed the name of the park.
