Peace
Peaceful, Tranquility, Tranquil, Heian
Something is flat and relaxed. That is you. What words does that describe? To me, that would be peace and tranquility. Just imagine something that is flat and relaxed, like a field of grass with happy people in it. It's so peaceful! It's so tranquil! This is also the way you write the Heian period of Japanese history.
へいあん
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
平安じだいはいつですか。
When was the Heian period?
