The definition from Yabla (which is prettier in Ninchanese ):
- to discuss passion and talk of love (idiom); to express love with terms of endearment
- billing and cooing
And to translate the sentence:
你的水准能跟四爷谈情说爱。
The first part of the sentence without translating 谈情说爱
would be something like:
Based on your level, you can 谈情说爱 with fourth Lord.
In this context, how should 谈情说爱
be translated?
