The Kwan Im Thong Hood Cho (more popularly known as the Si Ma Lu Guanyin Tang) is a Chinese temple located at Waterloo Street dedicated to Guanyin, the Goddess of Mercy as well as other deities such as Hua Tuo, the patron saint of Chinese physicians. The original temple structure was built in 1884, with major restoration and rebuilding works carried out in 1984 that saw the addition of a new facade. The temple is a popular site of worship, especially during the Chinese New Year period when thousands of devotees flock to the temple to be the first to plant their joss sticks at the stroke of midnight.
