Who wrote the Tiger Hill Dragon Tiger Leopard Bear?

On the white wall in front of Cui Yongshan Villa, Tao Maosen has four characters of "Dragon, Tiger, Leopard and Bear", which is said to be the ink left by Tang Bohu and Zhu Zhishan in a calligraphy competition here. Dragon and Tiger was written by Zhu Zhishan, and Leopard and Bear was written by Tang Bohu. However, according to textual research, it was made by Tao in Guilin in October of the eighth year of Xianfeng in Qing Dynasty (AD 1858). There are dragons, tigers, leopards and bears at the entrance of Cui Yongshan Villa. The garden is built on the hill and on the roof. There are "Bao Weng Xuan", "Linglan Jingshe", "Hot Spring Pavilion" and "Moon Drive Xuan" in the park.
