He is considered powerful to hold 14 rounds of concert. Everyone will understand and hope he will have a speedy recovery. He feels touched and it is suffering for him. Andy loves his fans and makes this decision as a result.”

Andy also revealed his wife, Sammi Cheng (鄭秀文) lost her voice while opening her concert previously and felt heart pain: “I helped my Singaporean friends to buy Andy’s concert tickets for 29th December and we had dinner on 28th December.
