What kind of damage was done to the carved stones embedded in the outer north wall of the ground floor of Penglai Pavilion?

The outer wall of the north wall of the ground floor of Penglai Pavilion is inlaid with three large-scale carved stones: "Blue Sea Breeze", "Sea Calm Waves" and "World Sea Mirror Clear". The stone carving of "Blue Sea and Breeze" is the calligraphy work of Lu Qiguang, a calligrapher of the Qing Dynasty. The stone carving "Hai Bu Yang Bo" was unfortunately hit by a bullet during the Sino-Japanese Sino-Japanese War of 1894. The word "bu" was damaged, and its scars are still visible. A group of precious calligraphy and paintings such as the ink bamboo pictures painted by the talented Nanhai scholar Zhao Ziyong on the pink wall have also disappeared from the world.
