If you can't make an account on Taobao or Weidian, or don't want to for any reasons, here are a few tip to get around.
Firstly: Use the RepArchive "My Agent" Browser Extension. This redirects you to your agent, so you don't get into a situation where you have to login on Taobao or Weidian.
Secondly: Use the RepArchive Weidian Search Engine. (Weidian only). This is a general tip, because even with an account, you couldn't replicate this feature.
