Google adwords on mobile
Re: Google adwords on mobile
Welcome to AdWords Community.
According to the information I could find - “Chan Thap Thanh” is a game which was released by ThapThanh. This game has millions of users in Vietnam market.
That being said the term "Chắn thập thành" should be a trademark of ThapThanh, and if that is the case you won't be allowed to include it in your ads. However, you can use it as a keyword.
