Chai Jia Lane is located in the northwest of the city, starting from Shuiting Street in the north and reaching Ningshao Lane in the south. The alley is very narrow, but it also has some origins. According to Qu County of the Republic of China. The sixth page of "Family Outlook" records: Xiang Chai's family was later the emperor, and his name was Chongyi Gong in Shu Xia. Take over the copyright of the second throne in Feng 'an, Jingfuyuan in Quzhou, and Sun Sui's family in Qu. "Chai Jia Lane, like Lujia Lane and Feijia Lane in the street, is named after the surname. It has one characteristic: first, it is not a common people; second, people in the lane don't have to be surnamed Chai. This is very different from rural villages named after surnames. In rural areas, such as Daijia, Qijia, Fang Jia, Huangjia or Xujiawu, they are generally large families, or surnames are dominant. Some people can come up with a huge family tree. A family in the TV series "Brothers Company" came to the mountains and forests to escape the war, but the family didn't even have a physical surname.

According to Qing Jiaqing's Xi 'an County Records, Xichaijiaxiang in this county has been prosperous for 47 years.

Time flies, and now the "Chai Jia" clan may have disappeared in Chai Jia Lane. The sheriff's association building in Song Guangli's hometown has disappeared, and so has Cai Ying Elementary School. However, this may be related to Zaomu Lane, which is only one kilometer away from Chai Jia Lane, and a new primary school has been built there. Unfortunately, it has not been confirmed. There are some ancient buildings in the alley, and the Chinese characters of chess and cards can be faintly seen on the walls. I think this is where the chess friends meet. According to Zhou Yaqing, who grew up in Chai Jia Lane, "Chai Jia Lane has two characteristics: First, there are many wells, and seven out of ten households have wells. For example, there are wells on No.3 and No.4, and there are also wells diagonally opposite. The other is that most of the old people in this alley live for a long time, and the old people in their eighties and nineties are very ordinary. " Many wells must have something to do with the water in Qujiang. What is the reason for longevity? During the Cultural Revolution, Chai Jia Lane was once renamed Harmony Lane. Living in harmony with neighbors and the peaceful and special environment in deep alleys may be the important reasons for the longevity of the elderly.
