有条件的可以考虑捐下 wikipedia

https://en.wikipedia.org/wiki/Main_Page

Dear readers,

We'll get right to it: This week we ask you to help Wikipedia. To protect our independence, we'll never run ads. We survive on donations averaging about ¥1,500. Only a tiny portion of our readers give. Now is the time we ask. If everyone reading this right now gave ¥700, our fundraiser would be done within an hour. If Wikipedia is useful to you, please take one minute to keep it online and ad-free. We're a small non-profit with costs of a top website: servers, staff and programs. We serve millions of readers, but we run on a fraction of what other top sites spend. Wikipedia is something special. It is like a library or a public park where we can all go to learn. Wikipedia is written by a community of volunteers with a passion for sharing the world’s knowledge. Please help us end the fundraiser and get back to improving Wikipedia. Thank you.
