Much attention was devoted to turning works released online into physical books.

China's most popular question-and-answer social-network website, Zhihu.com, published its second book, Jin Qian You Shu (Money Has Its Way), in partnership with China Citic Press. Its first book on starting businesses proved successful last year.

The new book is a compilation of 15 authors' answers to questions about finance and money management that received nearly a million "likes" on the website.

Its subtitle reads: An Elective Finance Course with 987,433 Likes.

Zhihu claims the content was selected from answers to more than 300,000 questions posted by 12 million registered users, who include entrepreneurs and intellectuals.

Questions about finance became hot topics on Zhihu over the past year because of the surge of online fund-management platforms and the stock market's recovery.

"We created this book by screening to determine the best content," says Cheng Yuan, who co-founded the website in 2011.

The book has already sold 100,000 copies since presale online orders began two months ago.
