There are several long hutongs-Prime Minister Hutong, Mishi Hutong, Panjiahu Hutong, Fenfang Liuli Street and Jiajiahu Hutong. Jiajiahu starts from Guo Zi Lane and ends at the middle section of Nanheng East Street in the south. According to historical records, it has been called this name since the Jin Dynasty, and it was also called Jiazi Hutong in the Ming Dynasty. In the Qing Dynasty, the homonym of "Ge" was "home", that is, it changed back to Hutong, and it has not changed since then. Jia Hutong has a long history and many halls, among which the famous ones are Henan Hall, Hall and Fujian Puyang Hall. There have been many famous literati here, such as Lin Zexu, who lives in Puyang Hall in Fujian. In the thirty years of Daoguang (1850), Zeng Guofan lived here; Hong was a famous economist in Qing Dynasty. He moved here in forty-six years, and his population theory was earlier than Malthus's. Wu, a famous novelist in the late Qing Dynasty, was born here with the book Wonders Seen in Twenty Years. As for the characters in the stand-up comic "Fake Expert" said by crosstalk master Liu Baorui, they also live in Jia Hutong, which is just a joke.
