Why did Eva Choo choose to tour in Guangdong some time ago? Why not choose other provinces and cities?

Those aren't solo concerts, and the choice of where to be is all up to the organizers.

Also, Yi Ting's performance agent is in Guangdong, and there are relatively more Ting fans in Guangdong, so most of the previous ones were chosen in Guangdong. If you look at the change in popularity in the future, the chances of performing in other regions will be greater.
