He didn't.
He Cheng is taking He Tian to the hospital. He Tian is refusing to go and unbuckles and gets out of the car ( that's why his brother says 'Hey' ) ...
He Tian walks out of the car where it happens to be that place. They have their small chat and obviously He Tian is not well. It's windy. We heard the radio announce it was windy. That's his brother saying, let's go back. He Cheng never took him to the beach, never intended to do it. They ended up there because He Tian got out.
exactly.. makes no sense. lol.
Why did he take him to the beach when they were headed for the hospital ? ┑( ̄Д  ̄)┍
