I have been to Zhangjiakou.

He is studying the traditional Baijiaxing (Hundred Family Surnames) of China.

He is participating in international negotiations as a member of the School of Diplomacy.

My favorite starter Pokémon are Bulbasaur, Charmander, and Squirtle.

Kazue is my best friend.

He is secretly active as a hentai manga artist.

We need to minimize the system's downtime.

The albatross is a seabird with long wings.

Since he is always laughing, it can be said that 'fortune comes in by a merry gate'.

He spent his money as quickly as 'a duck comes bearing green onions', which means a fool and his money are soon parted.
