This is just a slogan design. Of course, other milk can't be called Telunsu. Because the trademark has been registered, the industrial and commercial bureau has put it on record, and other milk is afraid to scream, which is infringement. Moreover, every kind of milk has its own taste and nutrients, and it can't be the same. Twins can tell the difference. Just like you, there is only one in the world, and your parents are named after you. No one can be exactly like you. Therefore, not all milk is called Telunsu.
