Introduction to carvings: The flying corners outside the building are decorated with exquisite carvings. The three characters "Jiaxiu Tower" on the forehead of the building were written by Xie Shiqin during the Xuantong period. During the ten years of turmoil, three characters were lost, but two pieces engraved with the characters "秀" and "楼" were later recovered. Based on past photos, the characters "A" were written on them and hung on the outside of the top floor in the original style.
