Yang Chen usually writes in German: Yang Chen (first name before surname).

On some occasions, such as when filling out a form, or even when signing an important signature, you will be required to write your surname first and then add a comma, that is, Chen and Yang.

Yang generally means ocean in Chinese names, while German Ocean means (das)Meer. As a surname, Chen can't be translated, so it is called Milchen. However, it is strongly recommended to use hanyu pinyin as the original name.

If you still don't understand, please ask.
