Hong cun, located 6 kilometers southwest of Tsinghua Town, Wuyuan County, is a village named Hong. According to Village Tree, Hongcun was founded in the early Northern Song Dynasty, and the first person who moved here was named Acer. The village is located in a narrow and winding valley, where a stream flows by and three stone bridges cross it. There are clan buildings such as Guangyutang and Sanshutang in the village, and inscriptions such as "Tea Rules", "Healthy River" and "Never Prohibit Gambling" have witnessed the clan system. In ancient times, the village was rich in "pineapple tea", and the villagers were healthy and lived a long life, so they were called "Longevity Guli". Surprisingly, in such a remote mountain village, there is actually a home of "Dr. Four Seasons", which shows that Wuyuan's book "Ten Villages, Not Worthy of Reading" really deserves its reputation.
