GDJYB is a female maths-folk band from Hong Kong. Their music are produced in the language of Hongish (Hong Kong style English), which is a mixture of Cantonese and English unique to the city of Hong Kong. Current line-up of the band include Soni Cheng (Guitar), Heihei Ng (Drums), Soft Liu (Vocal), and Wing Chan (Bass).
The band started in summer 2012 when Guitarist Soni came across Vocalist Soft through an online music forum, who later introduced Drummer Heihei into the group and began jamming as a trio. The name GDJYB is taken from the acronym of their Cantonese name “Gai Daan Jing Yuk Bang”, a Chinese dish made of steamed egg & pork.
