Expressing "how about" with "yaobu"

要不 (yàobù) can have a number of meanings depending on how it is used.

要不 as to mark possible choices

要不 can be used to offer "either/or" choices to others, similar to 或者.

• 你 要不 看书 要不 听音乐 。Nǐ yàobù kànshū yàobù tīng yīnyuè.You can either study or listen to music.
• 要不 你 做，要不 我 做，但是 一定 要 做 完。yàobù nǐ zuò, yàobù wǒ zuò, dànshì yīdìng yào zuò wán.Either you do it or I do it, but it's definitely going to be done.

Another word that can be used in a similar pattern is 要么, with the difference that 要么 can only be used to list the either/or choices available to oneself as well as the choices available to others.

要不 used for suggestions

要不 can be used as an indirect way of giving a suggestion, as the speaker is using 要不 to seek consent of the listener.

• 一个人去看电影没意思，要不 我们 一起 去 吧。Yī gè rén qù kàn diànyǐng méi yìsi, yàobù wǒmen yīqǐ qù ba.It's no fun to go to the movie by myself.How about we go together?
• 要不 我们 去 逛街 吧，比 在家 睡觉 有 意思。Yàobù wǒmen qù guàngjiē ba, bǐ zàijiā shuìjiào yǒu yìsi.Let's go shopping. It's more fun than sleeping at home.

要不 means otherwise

要不 can also be used to mean otherwise:

• 你 快点 打电话 给 他，要不 他会 很 担心。Nǐ kuài diǎn dǎ diànhuà gěi tā, yàobù tā huì hěn dānxīn.I need to call him soon, or he'll start to worry.
