“Because” in Chinese is 因為因为yīnwèi, and “so” is 所以 suǒyǐ. Put them together and you get 因為因为…所以…, the most common way to link a reason with its result.
一 The Basic Pattern
因為因为 + Reason，所以 + Result
因為因为yīnwèi introduces the reason, and 所以 suǒyǐ introduces the result. In English you use just one of them (“because” or “so”), but in Chinese they usually appear together. Chinese also likes to put the reason first and the result second.
因為因为今天天氣天气很好，所以我打算去公園公园野餐
The weather’s nice today, so I’m planning to have a picnic in the park.
因為因为頭头很痛，所以昨天我沒没去上班
I didn’t go to work yesterday because I had a headache.
因為因为大家都說说這個这个很好，所以我就買买了
Everyone said this was really good, so I bought it.
因為因为你昨天沒没來来，所以我把票送人了
You didn’t come yesterday, so I gave the tickets away.
The subject can go before 因為因为 too: 我因為頭很痛，所以昨天沒去上班我因为头很痛，所以昨天没去上班. When the subject is the same in both halves, you don’t need to repeat it after 所以.
二 Can I Use Just 因為因为 or 所以?
Yes! You can use just one of them. It sounds more casual, and it’s very common when chatting with friends.
Result，因為因为 + Reason
好餓饿，因為因为我今天還还沒没吃早餐
I’m so hungry because I haven’t had breakfast yet today.
With only 因為因为yīnwèi, the result can come first, just like in English.
我今天不回家吃晚飯晚饭了，因為因为老闆老板突然說说要開會开会
I won’t be home for dinner today, because my boss suddenly said we have a meeting.
他昨天很生氣生气，因為因为他的錢包钱包不見了不见了
He was really angry yesterday because his wallet went missing.
Reason，所以 + Result
下雨了，所以今天的散步取消了嗎吗？
It’s raining, so is today’s walk cancelled?
我昨天很累，所以很早就睡了
I was really tired yesterday, so I went to bed early.
你不去，所以買买五張张票就好
You’re not going, so we’ll just buy five tickets.
颱風台风來来了！所以明天不用上班！
A typhoon is coming! So no work tomorrow!
Typhoon day off!Did you know Taiwan has typhoon days off? When a typhoon is on its way and could make getting around dangerous, local governments announce a special day off. Schools and many offices close, and everyone is told to stay safe indoors until the storm passes.
But let’s be real: Taiwanese people always find a way to make the most of their time. Instead of staying cooped up at home, lots of people head to the movies or the department store. It’s our little secret, don’t tell anyone! 😉
三 Common Mistakes
❌ 因為因为下雨，我所以不去了
✅ 因為因为下雨，所以我不去了
所以 suǒyǐ is a conjunction, so it goes at the start of the result, before the subject.
❌ 我生病了，因為因为我沒没去上課上课
✅ 我生病了，所以沒没去上課上课
Careful which word you pick! With 因為因为yīnwèi, this says “I got sick because I didn’t go to class.” Getting sick is the reason, so the result needs 所以 suǒyǐ.
❌ 所以我沒没去上班，因為因为頭头很痛
✅ 因為因为頭头很痛，所以我沒没去上班
所以 suǒyǐ always comes with the result in the second half. If you want the result first, drop 所以: 我沒去上班，因為頭很痛。我没去上班，因为头很痛。
