Che Kung is the Hong Kong deity whose birthday is associated with the second day of Chinese New Year.
Che Kung was a military commander associated with the Southern Song dynasty, traditionally dated to 1235–1330. Folk tradition credits him with protecting people from disorder and disease, leading Taoist worshippers to regard him as a protective deity.
The second day of the first lunar month is regarded as Che Kung’s birthday, especially at Che Kung Temple in Sha Tin. Worshippers commonly burn incense, seek divination, and turn temple pinwheels for good fortune. A frequent mix-up is the third day: some celebrations are held then, and modern festival observances may emphasize it, but the traditional birthday association is the second day.
