Andy Lau and Raymond Wong wrote the lyrics for the disaster relief theme song "Vast Sea, Boundless Sky".

A 7.8 magnitude earthquake struck Sichuan not long ago, and the disaster situation is severe. In order to help their compatriots on the mainland, Hong Kong's entertainment industry has held various fundraising activities. Yesterday (May 14), the Hong Kong Artistes Guild also held an emergency meeting, announcing the launch of a program called "The May 12 Care Action by the Entertainment Industry of Mainland, Hong Kong, and Macao." Participating organizations include TVB, Asia Television, and multiple radio stations, all working together to raise funds for disaster relief. Eric Tsang appealed to all artists and singers in Hong Kong to record a theme song at RTHK tonight for this great disaster, sending blessings to the victims.
