The transliteration of Chen's English name is the same as pinyin, so it is translated into English:

Chen,

The Child's Eye

or

Chen,

swallow

pincers

Generally speaking, when introducing yourself in English, you will say your first name before your last name:

The Child's Eye

the Chen Dynasty

or

swallow

pincers

the Chen Dynasty

At present, most passport translators spell the names of two words (children's eyes), so the most common translation is:

Chen,

The Child's Eye
