Why can't I find Wenzhou Hongkai Hotel on the US Mission?

No agreement was reached with the official of the US Mission.

According to official website's inquiry of Meituan, Wenzhou Hongkai Hotel can't be found in Meituan because there is no agreement with the government, so there is no cooperative relationship and it can't be registered in Meituan.

You can find another hotel to make a reservation according to Meituan Hotel, as long as there is a cooperation agreement.
