[There are 678 problems in total, and it really took me a lot of time in proving and typing. Some are rounting verifications, some are interesting generalizations of well-known results, while others are really chanlleging research projects. Sometimes I took one weak or more to think out only one problem. If you whish, you could just pay 333 Yuan (approximately 0.5 Yuan per one problem) to email@example.com via alipay (after you have paid, please send me an email to firstname.lastname@example.org with the deal serial number), then I shall send you a parcel by Ems or other express companies.]
