Chinese bottles immediately oxygen os. All languages. The difference is the charger and the 4g and 5g speed where the different frequencies are pulled together to create 300-500 Mbit Internet. But in Germany that hardly exists. I own China OnePlus 12 myself :)

Ah yes, and Chinese doesn't have eSIM

Many European languages, including German, are available in the global version. With the Chinese version, the mobile is only limited to Chinese and English. And the 4G and 5G bands in the CN version are not all set up for Europe. This means that you may not have reception in certain places, for example.

However, you can also flash a global Rom on the Oneplus 12 CN version.
