My friend said that drinking more coffee will definitely make you feel awake, but I said, “Not necessarily — sometimes it makes me sleepier!” Let’s learn how to say “not necessarily / not always true” in Chinese.

不见得（ bú jiàn de)

Hello，大家好，我是Janine。Hello, dàjiā hǎo, wǒ shì Janine.Hello everyone, I’m Janine.

昨天朋友跟我说：Zuótiān péngyou gēn wǒ shuō:Yesterday, my friend told me:

“多喝咖啡一定会提神。”“Duō hē kāfēi yídìng huì tí shén.”“Drinking more coffee will definitely make you more awake.”

我笑着说：Wǒ xiào zhe shuō:I smiled and said:

“也不见得吧，我喝多了反而更困。”“Yě bú jiàn de ba, wǒ hē duō le fǎn’ér gèng kùn.”“Not necessarily — when I drink too much, I actually get sleepier.”
