Is the Tian Yan constellation a symbol of the southern sky class?

One of the polar constellations in the southern sky. Located in the south of the South Triangle, next to the South Pole, China can only be seen in Nansha Islands. Its main feature is that three stars form a narrow triangle at the eastern end of the I-shape. This narrow triangle is located at the midpoint of the second-class bright star triangle in the east corner of the South Triangle. Since there is no bright star like Polaris in Antarctica, this triangle in Tian Yan constellation has become one of the important signs to determine the South Pole. As long as we find the southern triangle and the narrow triangle of Tian Yan constellation, we can determine the position of the southern celestial pole. Cygnus first appeared in the world's first all-star map drawn by German amateur astronomer Bayer in 1603. Tian Yan is actually the image of a bird of paradise. Because it is produced in Papua New Guinea in the East Indies, the original name of this constellation is "Indian Bird".
