Send two banners when the building is completed. Yes, I will definitely send two. There are two banners, one with the name of the donor or the name of the company on it, and the other with a congratulatory message, such as Zhang San's opening to the outside world and prosperity. For example, I warmly congratulate a company on its opening. The other is about Dongxing Real Estate Co., Ltd., which opened its doors and prospered, and achieved great success on the next level.
