請將下面這段話翻譯成英文：
送禮在中國是種常見禮儀（etiquette)，人們借此表達對友誼、款待的感激或感謝。然而，中國送禮和收禮的禮節(jié)與其他文化大為不同。在很長一段歷史時期里，當朋友送禮物或款待自己時，有禮貌的人會回報朋友的關心和好意。他們會挑選一個合適的場合禮尚往來，因為他們認為這對加深關系很重要。禮物的選擇取決于兩人的關系，這與世界上大多數文化都相同。
參考答案:
Giving gifts in China is a common etiquette used to express appreciation or gratitude for friendship or hospitality. However, Chinese etiquette of giving receiving gifts differs a lot from that in other cultures. For a long time in history,people of good manners would return favors and kindness when receiving a treat from a friend. They would pick up a suitable occasion to offer back as they regard it important to strengthen their relationship. As it is the same with most cultures in the world, what to give depends on their relationship.
