Introduction to Kim Koo Refuge: In April 1932, South Korean national hero Kim Koo took refuge in Jiaxing after organizing the "Hongkou Park Explosion" incident in Shanghai that shocked China and the world. Zhu Zanqing's niece and the daughter-in-law of Jiaxing Kuomintang veteran Zhu Fucheng, Zhu Jiarui, escorted Mr. Jin Jiu to Nanbei Lake for refuge regardless of personal safety. After living in Zaiqing Villa in Nanbei Lake for half a year, Jin Jiu finally escaped safely, creating a good story in the history of Sino-South Korean friendship and writing a glorious page for the friendship between the Chinese and Korean people and the anti-fascist struggle.
