Download link: Visual Studio Code - Code Editing. Redefined
The download from the official website is too slow. It will be much faster to use the domestic mirror server to download. The setting method is:
Right click on the vscode that is being downloaded
copy download link
Select copy download link 
Then replace the az764295.vo.msecnd.net in the download address with vscode.cdn.azure.cn to use the domestic mirror server to accelerate.
