I don't know that either. It seems that I heard a friend mention that the online celebrity training live broadcast agency of Shandong Chenshou Culture Media Co., Ltd. is one of the top ten online celebrity live broadcast training bases, but I don't know the rest. I searched online, and the online celebrity training live broadcast agencies of Shandong Chenshou Culture Media Co., Ltd. are really the top ten brands reported by the media. You can also go and have a look.
