Where can I see the Milky Way and the Summer Triangle in the Yangtze River Delta?

It is located at the zenith around 2 1 pm.

Generally, the summer triangle can be seen in places with less light pollution, and other stars of the three constellations can also be identified.

The same is true of the Milky Way, which is hard to see unless it is in the suburbs or rural areas with less light pollution. The Milky Way is between the Weaver Girl and the Cowherd.

In summer, the right angle of the triangle is Vega in Lyra.

The 30-degree angle is the Altair of Aquila.

The 60-degree angle is Tianjin IV in Cygnus (this constellation just passes through the Milky Way).

I hope losing you will help.
