The dividing line of tropic of Capricorn

The Tropic of Cancer indicates that the Tropic of Cancer in Tarnum is the dividing line between tropical and north-south temperate zones. The area between the Tropic of Cancer and the Tropic of Capricorn is tropical, where the sun shines directly and gets the most heat. The area between the Tropic of Cancer and the Arctic Circle (66 34' north latitude) is the north temperate zone, and the area between the Tropic of Cancer and the Antarctic Circle (66 34' south latitude) is the south temperate zone. In temperate regions, the sun can only be oblique all the year round, and the heat obtained is moderate. Most of China is located in the north temperate zone, which belongs to the temperate climate.

Before 1985, the only sign of the Tropic of Cancer on the earth's surface was the "Tropic of Cancer" stone tablet in Chiayi County, Taiwan Province Province, China, which indicated that the Tropic of Cancer passed there. 1985 July 15, China built another 27.55-meter-high Tropic of Cancer landmark tower in Conghua County, Guangdong Province.

The tower is in the shape of a rocket, with arches in the east, west, south and north. Marble is paved in the middle of the tower bottom, and red agate is embedded in the middle dot to show the direct position of the sun. At the top is a copper ball with a diameter of 120 cm, and there is a round hole in the middle of the ball for verification of direct sunlight.
