Who can introduce the stars that can often be seen in the northern hemisphere sky? How to identify them? How to find them? What is the approximate time of appearance?

I can tell the landlord that it is not fast to know the starry sky. In order to know the starry sky, every sunny night in high school, I will go for a walk in the garden of the community and see my friends in the sky. Four seasons, just made friends with the stars in the sky. Now that I think about it, it is one of the best memories of high school, but how many times have I been difficult and lost? People who have not experienced it can't understand it.

Glanced at roughly:

Winter, now the starry sky, might as well search Baidu pictures for the hexagon in winter. Pay attention to the following bright stars.

Betelgeuse-Orion

Bi Su Wu-Taurus

Capella auriga

Beihe III- Gemini

South Khesan-Little Dog Constellation

Sirius Canis major

Spring. Now it appears in the east after about 12. Baidu picture "Spring Arc" or "Spring Diamond". Pay attention to the following bright stars.

Xuanyuan XIV-Leo

Arcturus.-Chief.

Andromeda, the star of the horn.

The Big Dipper (Shu Tian, Tian Xuan, Tianji, Tian Quan, Yuheng, Kaiyang and Yaoguang)-Ursa major.

It is not easy to observe the starry sky in summer and autumn now, until the Beidou dries up and leans south.

The map is shallow and I know nothing about it.
