Mamoru is my best friend.

The Spring and Autumn Warring States period is a part of Chinese history.

I want to travel to many countries.

He works as a bodyguard for an important politician.

He was hired to escort the important guest.

We are here to escort the ambassador.

He plays a very important role as the team's middle blocker.

I visited Zhongwei, a prefecture-level city in Ningxia, China.

In ancient times, an important military base was located in this area.

My country is blessed with beautiful nature.
