Joe Ma (馬德鐘) sang the theme song of the drama, Life on the Line (跳躍生命線) at an event as the guest performer on 7th January 2020. Asking when his son Xiang Ma (ç) will be resuming his studies in Australia, Joe said: “He is currently enjoying the school holidays and will be going back in February. However, it depends on Australia fires and hopefully it will stop soon. My son and I feel very heartbroken upon seeing the trees and animals are affected, and it is a pity that the beautiful nature is destroyed.”
