AA制还是一起付

zài在zhōng guó中国，péng you朋友yī qǐ一起chī fàn吃饭，shéi谁fù付qián钱shì是gè个yǒu yì si有意思de的wèn tí问题。

In China, when friends eat together, who pays is an interesting question.

rú guǒ如果shì是yǒu rén有人zhǔ dòng主动yāo qǐng邀请，tōng cháng通常shì是yāo qǐng邀请de的rén人fù付。

If someone did the inviting, usually the inviter pays.

rú guǒ如果shì是tóng shì同事suí biàn随便chī吃gè个wǔ fàn午饭，hěn很duō多rén人xí guàn习惯gè各fù付gè各de的。

For a casual lunch between colleagues, many people are used to paying separately.

zhè这zhǒng种gè各fù付gè各de的fāng shì方式，xiàn zài现在nián qīng年轻rén人jiào叫「AAzhì制」。

This split-the-bill style is what young people now call AA.

dàn shì但是rú guǒ如果shì是qìng zhù庆祝shēng rì生日huò zhě或者shēng升zhí职，bèi被qìng zhù庆祝de的rén人yī bān一般bù yòng不用fù付。

But for a birthday or a promotion, the person being celebrated usually does not pay.

yù dào遇到bié ren别人qǐng kè请客，xià cì下次jì de记得huí回qǐng请，zhè yàng这样guān xi关系cái néng才能cháng jiǔ长久。

When someone treats you, remember to treat them back — that is how a relationship lasts.

rú guǒ如果shí zài实在bù不què dìng确定，kě yǐ可以xiān先wèn问yī一jù句「zhè这cì次zěn me怎么suàn算」。

If you are really unsure, you can ask first: how are we doing this one?

zhí jiē直接wèn问bù不huì会xiǎn de显得xiǎo qì小气，fǎn ér反而néng能bì miǎn避免wù huì误会。

Asking outright does not look stingy; it actually avoids misunderstandings.
