Tsui Sing Lau pagoda at yuen long is the only ancient pagoda in Hong Kong that still exists. It is believed to be built by Tang yen tone of the seventh generation of the prominent Tang family there in 1486. It has a hexagonal shape and 3 storeys. The top storey is dedicated to the worship of the "文魁星" or star of knowledge or more exactly number one in exam. "Tsui Sing" simply means attracting the star. The star god would help students to be successful in public examinations. In ancient China, it was the only way to become government officials. Many Hong Kong residents took part in these examinations until the end of the Qing dynasty. Some even travelled north to Canton where exams at a higher level took place.
