Wuhan ancient and modern Bao Tong called me and asked me to auction cross stitch. Is it reliable?

I also posted some cross-stitch drawings of Chyi Chin's calligraphy and painting embroidered by myself on the Internet, with a price of about 80,000 yuan (370* 150). Wuhan ancient and modern Bao Tong also called me and told me that it could sell for 200,000-250,000 yuan, and there were ready-made buyers there. I only received 15% commission after listening to it. I was ecstatic. I just heard that the account manager told me to sign the contract first and ask me to pay a deposit of 3.6W, which is 20% of the reserve price (18W) set at that time. This seems reasonable (I really doubt whether she was a professional pyramid scheme before). She also promised that 100% can be closed, and the deposit will be fully refunded after the transaction. If it cannot be sold, and so on. . . . . . . . You have a good plan, I have a wall ladder. ) If it can be sold at 100%, do you still need to spend so much effort? Just accept it according to my online price of 8W. Don't you earn a lot? There will be no pies falling in the sky for no reason, and there is the sentence downstairs, "Let it sell, and everything that sells high is its;" Or let it find a buyer to sell and then give it a commission. In short, (1) don't pay first (2) pay first. Others are impossible. " Always ring the alarm bell of being cheated! ! ! !
