Topic1: Amazon.com Inc, the world's largest e-commerce company by market share, is to publish 122 books in printed and electronic forms. Meanwhile, one of its senior officials said that the collapse of traditional publishers is inevitable. The issue of books printed on paper disappearing in the future has aroused hot discussion among micro-bloggers.

TIANXING: I don't want paper books to disappear. I have a strong dislike of e-books.

XUEBAIPAO: I think books printed on paper might vanish gradually. I read more e-books than paper books currently, but I like the smell of books printed on paper.

XINRONGER: This is a topic that I discussed with my friends when I was at university and now I have begun to reconsider the issue. I don't think books printed on paper will disappear one day, but the number that are will become fewer and fewer with the rise of the Internet and technology.

QINGNIAOHALCYON: I think paper books might disappear some day, but not in our generation. Up to now, there is still much inconvenience attached to reading e-books.

Topic 2: According to official rules, car owners in Beijing whose vehicles have been stolen must win another license plate through the capital city's lottery system to buy a new one. If the stolen car is recovered, and the applicant was lucky enough to have won a new plate, he has to surrender one of his registration numbers.

Many citizens think this policy is unreasonable because people who have lost cars are already very unfortunate and the obligation to have to win another license plate is not fair on them.

PERLEV: The road to the lottery system is definitely an arduous journey.

LULALULABY: This regulation really sucks. I think it will be changed eventually.

GAOSHUAIMIYA: I've tried the lottery system for more than half a year and still I haven't won a license plate.

CUDDYZHANG: When administrative measures intervene in the market more than needed, there will always be surprises for us.
