老师让我们写一篇关于国庆活动的日记。

Lǎoshī ràng wǒmen xiě yì piān guānyú Guóqìng huódòng de rìjì.

The teacher asked us to write a diary entry about National Day activities.

国庆节的时候，很多人都会去旅游。

Guóqìngjié de shíhou, hěnduō rén dōu huì qù lǚyóu.

During the National Day holiday, many people go traveling.

国庆假期比较长，很多家庭会一起回老家看父母。

Guóqìng jiàqī bǐjiào cháng, hěn duō jiātíng huì yìqǐ huí lǎojiā kàn fùmǔ.

The National Day holiday is relatively long, so many families go back to their hometown together to visit their parents.
