汉英文写信的格式 Writing a Chinese Friendly Letter

到现在，只有一位网友问英文问题了，问答在下面。谢谢王小狼的问题！

So far (as of December 2nd) I've only received one single question for my English Chinese Q&A, which is posted below with translations:

王小狼问: "我想知道一些关于你们写信时所用的格式(包括信封),经常使用的一些开头语,结束语, 问候语 (只要是用来写给朋友不是写给长辈级人物的就行了),最好能多举几个例子啊。谢谢你哦期待你的回音！"

Wang Xiaolang asks: "I'd like to know some formulas that you guys use in letters (including on the envelope), some commonly used openings, greetings, closings (as long as it's used in letters to friends and not to older people), it would be great if you could provide some examples. Thanks, looking forward to your response!"

解答（关于用英文写信是我写的，关于中文的是王小狼写的）:
Answer (response for English letters by me, for writing Chinese letters by Wang Xiaolang)

[开头语 Opening]: Dear XX, (英文一般只能用这个开头语，不管是给谁写的) To whom it may concern, ("有关人物"-如不知道对方的姓名-中文有没有相等的格式?) 敬爱的XX, 尊敬的XX, (Two common openings for Chinese letters) XX: 你好！ (A common opening for a letter to a friend)

[信内容 Body]

[结束语 Closing] Yours respectfully, (在正式场合下用) Sincerely, (最常用的) Salutations, （比较正式的） Best wishes, （祝，好） Yours, （不正式的） Love, (给对象或家里人) See you! ( 那么,再见! 很不正式的) XX 此致敬礼! ("I hereby send my greetings!" - used in formal letters) 祝你(您)天天开心 (happiness every day) 祝你(您) 全家幸福 (happiness for your whole family) 祝你(您) 身体健康 (health) 那么,再见 (So, I'll see you - very informal) 就这样吧 (Alright then - very informal) XX (Notice that the name is indented in Chinese.)
