There are many different social media platforms used in China that can also be used to reach many people in China, but few have over 800 million users which can be reached on one platform for marketing services. This social platform is called QQ and it is one of the biggest social platforms around right now.
QQ is a great tool to use in order to share information to other users who have the same kind of interests as you (or as the thing you are trying to market). This saves a lot of time and allows other users to also share the information with their friends and family without having to reach out to individual users.
