Why does the whole building in the TV series belong to the same company? But we don't seem to have it in Shantou?

That's a group building. There are only a few here in Shantou. As you know, TV plays are also quite exaggerated.

Shantou Tianqi Culture is also a Shantou film and television advertising company, which is responsible for shooting corporate promotional videos, short videos of vibrato, short videos of toys and live movies. They also did a good job. You can consult longhu district of Shantou Tianqi Culture. Chenghai District has their company.
