We are focusing on the research and development of new products.

I conducted a research project as a summer vacation homework.

I live in Shenzhen.

Asami is my best friend.

He has a beneficent heart.

He is a very careful person.

The late autumn wind is rustling the leaves of the trees.

His words were profound.

He was so profound that it was difficult for us to understand his thoughts.

He is thought to be a greedy person.
