Shanghai's blues hour is when day turns to night in the evening

I watch the night view every day. It is said that the night view of Shanghai has a blue moment. In fact, the best time is not late at night, when the lights are turned off. The best time is actually in the evening when day and night change, the lights are on, and the surroundings are not so dark, with just the right blue and red tones. I hope everyone can see the colors they like.
