Yangliuhu Park is better. You can also take her for a walk along the Ganjiang River. If you want to go to Yangliu Lake, take bus No.2, No.3, No.4 and No.5 to Jianguang Cinema (sometimes you don't have to go to Jianguang Cinema on February, March and 4th, but you will definitely go), and then you can get there from that entrance. Hehe, my family lives near Yangliuhu Park. Wish you success!
