Where can I buy the whole class textbook bookstore of Yitong learning package?

Oh, hey. . . Looking for the source ~ "Yitong learning package" belongs to Yitong. Of course, you have to ask Yitong. As far as I know, it has distribution points all over the country, depending on where you are.

Suggest, the most direct way, call the customer service phone of Yitong to ask. I have called and consulted about preschool education equipment such as art children's learning bag, art children's activity area and art children's sports bag. It's a 400 number, but I forgot the details. On Yitong official website. Go find it ~ there is online customer service on the website, and online consultation is very convenient.
