Brief analysis: These two poems not only have feelings of parting, but also contain deep consideration of the traveler's situation and mood, and sincere wishes for cherishing the road ahead. For the farewell party, persuading the other party to "have more drinks" is not only to let friends take away more friendship, but also to delay the breakup intentionally or unintentionally and let the other party stay for a moment. The feeling of "going out to Xiyangguan for no reason" belongs not only to the traveler. Parting, I have a lot to say, but I don't know where to start at the moment. On this occasion, there is often silence. "Advise you to drink more wine" is a way to unconsciously break this silence and express the rich and complicated feelings at the moment. What the poet has not said is much richer than what he has said.
