This meeting notice of the Hok Kin Kongsi, part of the Ghee Hin Mother Lodge, summons its members for a meeting at the kongsi (society) lodge at night. The Hok Hin Kongsi was formed in 1850 and wielded considerable economic power in Singapore, while the Ghee Hin Kongsi was predominantly Hokkien and the largest Chinese secret society in Singapore in the 19th and early 20th century. Like all its other counterparts, the Hok Kin Kongsi saw its roots in the Tiandihui, a sworn fraternity comprising Chinese men with the common aim of overthrowing the Qing dynasty and restoring the Ming. With increased Chinese migration to Singapore, the local society became a form of mutual-aid and support, and various splinter groups (hui or kongsi) subsequently emerged among the main dialect groups.
