Textbooks with value less than 2000 Yuan but quantity exceeding 30, need to declare?

Hello, I will be bringing American: English, History, Science, and Math textbooks for primary school age students. There will be about 30-35 in total. The value of these items is less than 2000 yuan (I converted how much I paid for them in USD to RMB and got 1508 yuan). Will I have any issues bringing this number of books over with me? Should I declare them even though they are valued less than 2000 yuan?

I am not planning on bringing these books back with me when I leave China, they are for the children I will be working with and will be leaving them for the teacher who replaces me. I just don't want to run into any issues when I get China. Thank you so much.
