Dear, I will teach you the easiest way, such as watching XOXO. Look at the back of its album. If it is written in English, it is the original. If it is written in Guangdong, it is an imported version. Generally, the quality of the imported version is not ideal, but the price is relatively cheaper. Exo-m's Chinese albums are of course divided into original and imported versions. Just as we buy Korean albums, Korean fans want to buy China albums. They can't go to China to buy an imported version, so they must have the original version and an imported version for the China market. That's it. But if you want to contribute to your brothers, you'd better buy genuine ones, because they can be included in sales.
