How to see Gemini on a summer night?

Don't talk nonsense if you don't understand the first floor and the second floor. I have been observing Gemini 12 years, and I have never seen Gemini in summer. The reason is very simple, it is a winter constellation. The sun moves in Gemini in summer. How can you see it? In addition, it is enough to look at the constellation with the naked eye. Otherwise, the ancients didn't have telescopes. How do they define constellations? Gemini is basically rectangular. Winter is the best time to observe it.
