I enjoyed a picnic under the summer sky.

I have been to Ningxia.

Asuka is my best friend.

Natsumiko is my best friend.

Natsuki is my best friend.

Natsuna is my best friend.

The first day of the month is the beginning of a new month.

I will hold my birthday party on the fifth day of the month.

Every sixth day of the month, we go on a picnic as a family.

There is a test in two days.
