Mr. Tan is my best friend.

We often have picnics by the river on weekends.

We have a picnic by the river every weekend.

This room is very spacious.

He is somewhat naive due to his sheltered upbringing.

We will attend a wedding ceremony tomorrow.

My favorite history book is 'Shiji'.

We will attend the graduation ceremony next week.

It's difficult to recognize his face.

Next week, we will hold a first anniversary Buddhist memorial service for my father at our home.
