Red flag in front of Juyi Hall in Water Margin.

After Song Jiang officially became the leader of the Water Margin, he consulted with Wu Xuejue and Zhu Wu, the military advisers, set up a brand in the class, wrote the word "loyalty hall" in the big book, and changed the golden pavilion to a big platform, with three levels inscribed in front. On the top of the mountain stands an apricot yellow flag, which reads "For Heaven". On the other hand, the red flag has two sides with more than four words on it. A book "Shandong Tiger Leopard Wing" and a book "Hebei Jade Kirin" stand in front of Zhong Yi Hall.
