Leo Ku (古巨基) held his concert (we世界巡迴演唱會香港站part 2) in Hong Kong Coliseum at night on 11th April 2019. In order not to let the history repeat and causing any injury again, he rehearsed until 4am on 10th April and returned to Hong Kong Coliseum again after resting for a few hours: “It resembles to rehearsing for the whole night. Please do not worry and I have a good rest. I am full of energy and will perform well, as I promised my parent to complete 4 sessions of my concert safely. I do not want my mother to worry while watching my performance at the same time.”
