1. Find related websites or apps without watermark.

For example: anime garden, acgrip, nyaa. You can see a lot of cartoon resources without watermark here.

2. Find the animation with watermark and use the watermark removal APP to remove watermark.

I usually look for it from Weibo, or Taobao also has technicians who provide related services. This is a good method, but it will take some time.

3. Buy genuine comics or comics directly.

Generally, there is no watermark after handling VIP or purchasing corresponding resources. I think if you really need information without watermark, then buying genuine products is the most reliable.
