Personally, I believe a trip abroad should last at least one or two weeks. It usually takes a few days just to adjust to a new environment and culture, so if you only stay for a short time, you end up rushing from one place to another. With a longer trip, you have the chance to really explore, relax, and even build connections with locals or fellow travelers, which makes the experience much more meaningful.
个人认为,出国旅行至少应持续一到两周。通常需要几天时间来适应新的环境和文化,所以如果你只停留很短的时间,就会匆忙地从一个地方赶到另一个地方。旅行时间更长的话,你有机会真正地去探索、放松,甚至与当地人或其他旅行者建立联系,这会让体验更加有意义。
