I have been to Changchun.

The spring breed of silkworms has started making cocoons.

Spring and autumn are the seasons when the beauty of nature stands out.

We plan to move to a new house next spring.

Shunsuke is my best friend.

He is the wise and capable person of our team.

The park is beautiful with blooming flowers in late spring.

The whole family gathered for the New Year's celebration.

This mountain is steep, making it difficult to climb.

The steepness of this mountain is a big challenge for climbers.
