Introduction to the Bagua caisson picture: The caisson on the stage is beautifully painted and was painted by Guo Xinlin in the 53rd year of the Republic of China. Colorful algae decorations are dotted on the caisson, making it even more magnificent. Guo Xinlin's handwriting can be seen on the Shouliang of the caisson. There is also the handwriting of Huang Tiansu, a famous calligrapher from Lukang, on the inside of the square, which is of great artistic value.
