When was Guigang Cultural Square built? What's the building opposite?

It seems that it was built in January. I remember that Mid-Autumn Festival and National Day were the same day that year. The square just opened, and many people went to the square.

behind the stage? That stage? You mean the city hall building? The taller buildings nearby are the International Hotel, Post Office and Telecom Building. . It seems that the buildings over there are relatively tall.
