" biệt gọi là弟兄 " seems to be a mix of Vietnamese and Chinese, which may lead to confusion. If you're asking about a TV series named "别叫我兄弟" (Don't Call Me Brother), I'm sorry but I couldn't find any relevant information about it. Could you provide more details? For example, the actor, actress or the time it was aired might help me find the correct TV series for you.
