At the beginning, I thought it was a park to commemorate martyrs. I felt very atmospheric when I entered the park and paid tribute to the comrades who sacrificed for the cause of people's liberation. There is a Nianjiahu Lake which is very big. It feels like Xuanwu Lake in Nanjing Royal Garden. It can take two hours to have a good time. The speedboat inside is also very exciting. The park is free of tickets.
