"No. 7 Huaianli" in the old town of Jiangcheng in 2025 is a red brick building built in 1927 during the concession period, with a total of 6 floors and 72 households. The building has hidden Gothic cloisters and secret passages in the basement. It was once a missionary sanatorium and a mass disappearance occurred in 1943. There is a legend about the "cloister whisper" circulating in the building. The sound of metal friction can be heard late at night on the 15th day of the lunar calendar every month.
