Introduction to Wanbao Spring: To the north of Qingyi Pavilion, there is a stone tablet with the three words "Wanbao Spring" written in big letters. It is said that the person who created the monument is Feng Xitian, a descendant of the scholar Feng family who lived east of Laolongwan. There is a deep rectangular stone pool on the side of the monument with a flowing spring. Every winter, as the two buckets of the water-carrying team keep splashing water, thin ice forms on both sides of the stone street, which shows that there are so many water-carrying people. Because people had a custom at that time: whenever carrying water on festival days, they always threw a coin into the spring. This spring was named "Ten Thousand Treasures Spring" because of the many treasures found.
