Kang Yung Study Hall is one of the few examples of study halls built purely for teaching purposes. Situated in the Hakka village of Sheung Wo Hang in Sha Tau Kok, it was built by the Li clan in the early Qing Dynasty. It began as a small private school for 20 to 30 pupils and was rebuilt in the Qianlong reign (1736-1795) and renamed Kang Yung Study Hall. As it was constructed purely for teaching purposes, the architecture is simple but functional. It is a two-hall building with cocklofts, providing classrooms and living quarters and comprises a rectangular structure of green brick walls, with unfired mud-bricks and rammed earth for internal partitions. It was declared a monument in 1991 followed by a full restoration undertaken by the government. It is now open to the public.
