四季 (sì jì): สี่ฤดู; สี่ฤดู (ฤดูใบไม้ผลิ ฤดูร้อน ฤดูใบไม้ร่วง และฤดูหนาว)

There are four seasons in a year: spring, summer, autumn, and winter.

The changes of the four seasons make nature beautiful.

In places with distinct four seasons, people can experience different scenery.

This country is like spring all year round, very suitable for travel.

Kunming is like spring all year round.

Here the four seasons are distinct, and each season has unique scenery.

I like the changes of the four seasons.
