Welcome to China, hope that you'll have fun in Hongkong! Fans in China loves you, wish that the charity concert on the 16th will be a huge success. (希望能帮到您)
估计是用作祝贺、祝愿、标语之类用途吧。可以理解为:“长寿、长久和兴旺、发达”, 比如说: Wish you live long & prosper! (祝你长寿和成功!)但是这样说是以动词来表达,在英语里面感觉不是太好,建议用形容词/名词来表达会更恰当:“Wish you long live & prosperity/prosperous! ” 这样说符合习惯,常用。希望帮到你。
