As we all know, logging into Google in China is not very possible for various reasons, and Google Scholar is almost unusable, which is very embarrassing for academic partners. Thankfully, there are plenty of mirrors to help us out. Here is a short introduction to mirroring and a list of a few very good Google mirrors that I hope will help.
Mirror sites are multiple copies of a website placed on different servers, which may improve responsiveness and allow users to obtain information on servers that are less accessible or relatively faster, improving the efficiency of network transmission and the security of the site. The mirror must be kept up to date to reflect changes in the original station, and there are times when the original station is not in a position to connect into the high-speed line, while the mirror station is.
