1. Distinguish the true from the false by name: the name on the genuine Telunsu packaging box is Telunsu pure milk, but the fake one will be marked with the font of flavored drinks on the packaging box, and the font marked is particularly small, which can't be seen without careful observation.

2. Distinguish the authenticity by the integral code: there will be an integral code on the packaging box of genuine Telunsu pure milk, and scanning the integral code with WeChat will directly jump to the official website integral page of Telunsu, but the integral code on fake Telunsu pure milk cannot be scanned.
