Introduction to Xixin Spring: Xixin Spring means "washing things will make them clean, and washing the heart will make them clear." It was dug in 1916 and named by Mr. Rong Desheng. In 1983, it was dredged again, stones were added to the spring, and the famous plum blossom expert Professor Chen Junyu renamed the spring. The stone wall is newly engraved with "The Heart-Cleaning Spring" written by Rong Yiren when he was a boy.
