First, when I bought it, I signed two contracts, one was a commercial housing sales contract, which was filed with the Housing Authority, and the other was a supplementary agreement on commercial housing sales, which was not filed with the Housing Authority. I signed two copies in a daze. When I look at it carefully, there are many differences between the two contracts. The Supplementary Agreement particularly emphasizes that the conflict between the two contracts shall be subject to the Supplementary Agreement. I have communicated this matter with the Housing Authority. The Housing Authority said that it had never heard of the supplementary agreement, and the real estate license should be based on the sales contract.

2. When purchasing Allianz House, the commercial house sales contract stated the predicted area of 9 1.28 m2 and the property fee of 0.89 yuan/m2, but the delivery notice in August stated the predicted area of 93.55 m2 and the property fee of 1.2 yuan/m2. The developer's delivery notice clearly states that the area difference should be paid first, and then the annual property fee should be paid according to the property fee of 1.2 yuan /m2. Then hand in the key and check the room.
