Baidu ads are placed on high school tutoring books.

I am a high school student from Jiaxing, Zhejiang. This year, our daily homework is a set of exercises edited by our own school teachers, called "New Curriculum Standard Optimized New Study Plan", published by the Tibet People's Publishing House. Surprisingly, on the back cover of each book, there is an advertisement for Baidu! Moreover, the text in the search box in the picture is the name of the series, which seems to be targeted. It is currently unclear whether it is a connection between the school and Baidu, or between the publishing house and Baidu; or perhaps a unilateral action with no relation to Baidu (which is less likely). When I asked the teacher, they didn't know either... Recalling some of Google's previous moves in the traditional publishing industry, Baidu's approach is worth paying attention to.
