2.      When you need a book for study or for fun, what do you usually do first: buy it, borrow it from a library, or look for it online? Describe your habits.

I tend to look it online, because books are so heavy and big that it's not easy to take, especially when I have to move house.

Though I prefer the sense of touching papers when reading.

At first, I looked for books online. But I don't like feeling like I lose track of my reading progress, even with the page numbers shown. Physical books give me a much better reading vibe. So I turned to the library, but this only lasted for about half a year. The reason is that sometimes the books I want are not available. Now I choose to buy second-hand books. They offer both a lower price and a great reading experience. By the way, I bought three second-hand English books from Duozhuayu last week.
