赤道 (chì dào): equator (of the earth or a celestial body); celestial equator

Singapore is located about one degree north of the equator, so it is hot and rainy all year round.

The country name Ecuador means 'equator' in Spanish, because the equator runs right through its territory.

When the research ship crossed the equator, the crew held a simple celebration ceremony according to tradition.

Near the equator, the sun shines almost directly overhead on most days of the year, so there is no real winter there.
