MEDM was founded on 20 16, which was formed by the merger of China rap senior brother KnowKnow and Nanjing fashion brand EXPIRYDATE. The origin of the brand name is because when you get paid abroad, you often say "enjoy the money", and then you suddenly think of KnowKnow and adding a word in front of it, and the name MEDM comes.

MEDM injects the complete brand concept into the unique clothing concept and presents it to everyone, forming a brand culture led by the manager KnowKnow.
