Chinese name: 中午
Pinyin: zhōng wǔ

Characters: The first character 中 is an ideographic character. Originally in oracle bones, it is a picture of two flags planted on both sides of a land. Later the character evolved into a flag inserted into the center of a land. Now the character simply means middle.
The second character 午 was an image of a rice pounder in oracle bones. Now it simply means midday.
A literal translation of 上午 in English is middle midday.
