Signing ceremony refers to the activities that stars, writers or some famous people sign their names for supporters who buy their own works (music albums, books or other works) in public.
Signing ceremony can not only narrow the distance between idols and fans, but also be an important way of publicity.
Qianmai is a Chinese vocabulary, pronounced as qiān shòu, which means (author, singer, etc. ) sign and sell your own works, audio-visual products, etc.
