Classic Design Resources Collection

Don't look at how fast I've been updating my blog recently. Actually, I've been collecting those contents for a long time because I think I will be very busy in the coming week. I'm worried that some contents cannot be delivered to you in time, so I decide to release them all at once today. Of course, a lot of contents are very classic and worth learning and collecting. If any viewer wants to repost any of my posts, please include a link. Such efforts are worthwhile. I won't say much nonsense, let me simply summarize the ones I think are highlights.
