I don't know why it annoys me so much, but i see this ad on the Beijinger for at least a month now. Not only that, but the person keeps updating it every day. It is just a fu%&g 30 kuai pump! Who in their right mind is willing to spend so much time on trying to sell 30 kuai pump?!
I decided that tomorrow morning i'm going to call that person and negotiate the price to 20 kuai, in the evening i have dinner in that area anyway, so i will ask to test it as well.
