When I walked into my friend’s house, I smelled cake baking. No wonder it was so fragrant! Let’s learn how to say “no wonder / that makes sense” in Chinese.

难怪 （nán guài)

Hello，大家好，我是 Janine。Hello, dàjiā hǎo, wǒ shì Janine.

今天我去朋友家。Jīntiān wǒ qù péngyou jiā.

一进门，我就闻到很香的味道。Yí jìnmén, wǒ jiù wéndào hěn xiāng de wèidào.

原来她在做蛋糕。Yuánlái tā zài zuò dàngāo.

我说：“哇，难怪家里这么香！”Wǒ shuō: “Wa, nánguài jiālǐ zhème xiāng!”
