It is said that last year's book fair has tasted the sweetness of derivative products, and this year, limited sets of products for reading are launched, including mugs and business card holders, to match the books with the same color covers.

据现场工作人员介绍，书展去年就尝到了衍生品开发的甜头，今年更是推出了“限量同色系阅品套装”，包括马克杯、名片夹等，搭配销售同色封面的图书。
