1, I bought the pre-sale version of the American version in Taobao Mall, so as far as pictures are concerned, we bought the same model, which should be the pre-sale version of the American version, no problem.

2. Whether it is a pre-sale version of the US version can be distinguished by the following contents:

A. The color of the cover is purple, not green.

B there are two discs in it, one is a music CD and the other is a tidbit. Making? Yes? Goodbye? A lullaby. You don't have to open this. You can tell how many discs there are by looking at the back cover.

C. Song capacity: The US version of the pre-sale music CD has 18 songs. The Japanese version has 19 songs (knock another one'? Open? Paradise? Door); I haven't verified the Hong Kong version yet.

3. Because the package cannot be unpacked, the verification method may have certain limitations.

4. Attach the cover of the regular version for comparison.
