Certified Tongle teachers can use L0 electronic textbooks and online courseware for free.

The purchase of all Tongle physical textbooks is "optional." Since 2023, Tongle materials have been fully digitalized. As long as students have the electronic version, it will meet all learning and review needs.

The printing and mailing of Tongle physical textbooks are managed by the third-party platform Lulu. Lulu is a Print-On-Demand service, and the prices on the Tongle website are set at cost.

Shared textbook sections exist across two curriculum systems within the same grade (e.g., L0); no duplicate purchase is necessary. Some materials (such as recitation, famous quotes, etc.) are used across multiple grades and do not need to be repurchased.

"Premium Quality" and "Standard Quality" textbooks have the same content; the price difference comes from the printing materials. Please purchase according to your needs. For instance, if you have multiple children and plan to reuse the books, you might consider "Premium Quality."

Before placing an order, please search for "Lulu Coupon" online and look for coupons with the Lulu logo.
