After World War II, the Lu Guo Hall Gan Clan Association applied for re-registration in 1948. The Association resumed operations at the original location (on the second level of the Qian Mei Company) under the leadership of Gan Say Hong, Gan Hui Hoon, Yan Zhong Min, Yan Ke Ming, Yan Jin Gu, Yan Qing Si, Yan Gu Wu, etc. Every Qing Ming, they would visit Leng Kee Hill to pay respect to late Gans and dutifully swept their graves and weeded the grass-patches. Later a dispute among members over property purchase disrupted the growth of the Association. The Association failed to renew its licence and it led to a suspension of activities. In 1966, Gan Yue Cheng took charge of the situation and rallied his kinsmen to establish the Singapore Gan Clan Association.
