Why do members of the US delegation refund the money spent by the hotel?

The reason why the members of Meituan returned the money spent by the hotel is because the seller did not verify your Meituan coupon. There was a QR code cancellation when Meituan placed an order. Slow network speed loading will cause merchants not to write off, so members of the US delegation will refund the money spent by the hotel. Meituan is a technology retail company. Meituan implements the corporate mission of "helping everyone eat better and live better" with the strategy of "retail+technology".
