Help for help ~! Where can I repair Lenovo notebooks in Hangzhou?

I live in Cambridge, far from here. Except Lenovo authorized repair shop, it is not reliable anywhere. Get it there and let them plug in the K-treasure, so that they can detect what is wrong with the hardware. Go to the train station. Although it is far away, there are many buses to go to, which is very convenient. Lenovo authorized Hangzhou Gangshi Digital Technology Co., Ltd., No.2 Huancheng East Road 1 1-2, next to the railway station, and walked 65438.
