Haha, you read with the eyes of a true detective, @wakeupkitty.pal!

You are absolutely right about "Old Chen". In Chinese culture, adding "Old" (老 - Lǎo) before a surname doesn't always mean the person is biologically old. It is often a nickname used among close associates to show familiarity, experience, or seniority in the field.

As for the "his wrist" translation quirk, that's a fascinating linguistic difference! Chinese is a language that often drops pronouns. In the original text, it probably just says "Chen flicked [the] wrist." Because English grammar strictly requires a possessive pronoun there, the translation tool automatically forces a "his" into the sentence. When you translate directly to Dutch, the AI engine might process that missing pronoun differently!

It's incredibly fun to discuss these cultural and linguistic nuances with you. Brace yourself, the real action in the cyberpunk world is just beginning!
