The last trip to Hangzhou failed to see Songcheng's performance. This chance coincided and finally met. From the history of Hangzhou to the culture, Songcheng's eternal sentiment perfectly depicts the development of characters and cities in every detail picture. The pictures are so delicate that they are amazing. The matching lights, sound and special effects are all first-class. No wonder they are called a must-see performance in one's life. Indeed, some shocks must be witnessed with one's own eyes!
