Liar, definitely a liar. I was cheated. I paid 300 yuan's deposit and 800 yuan's property right deposit. There will be no pies in the world. Think about it, under the premise of no guarantee, the manufacturer is not at ease to give you so many pearls. If you take 10,000 strings of pearls and sell a string of 0.5 yuan, it will cost you 300+800= 1 100 yuan more. There will be no pies in the world. Take it as a lesson.
