我那时每天都写日记。

Wǒ nàshí měitiān dōu xiě rìjì.

At that time I wrote in my diary every day.

那时他还不知道自己想做什么工作。

Nàshí tā hái bù zhīdào zìjǐ xiǎng zuò shénme gōngzuò.

Back then he still didn’t know what kind of job he wanted to do.

那时天气很冷，我们都穿着很厚的衣服。

Nà shí tiānqì hěn lěng, wǒmen dōu chuānzhe hěn hòu de yīfu.

It was very cold then, and we were all wearing thick clothes.
