Behind the scene
I got below conclusion from the above video I cried when watching.
Many people thought being artiste is easy thing. But there is things behind the scene we don't know see is easy but behind the hard work who knows? What kind of problem and stress they face who knows? Without their hard wrok their effort we won't have nice songs to listen or even nice show to watch. Some of them need film show, practice dance or prepare for concert etc.. which cause them do not have time to sleep or even never sleep for days.Not only this also not enough time for friends and family.
On screen we see them cheerful but behind is that so? Sometime they might in good mood but because they are artiste they can't show out. I felt some times fans to them is important just a simple word 'jia you'is the power of let them continue walk down this tough road.
