I don’t know the exact amount, but if you have money, you should go to Jiaxing or Shanghai. The technology in Jiashan is really not that good. The price in Jiaxing is probably 2,000 to 3,000, and Shanghai is more expensive. Should it be Jiashan? It's not much cheaper, but it's a bit troublesome to go back and forth from other places. Now that I've decided to correct it, I always hope to get it better. I'm someone who has been there. I have experience. As for the time, it usually takes about 1 and a half to 2 years. (Jiashan time is very Short, there will be a little rebound)
