What is the longest day in the evening?

In the northern hemisphere where China is located, the sun shines directly on the Tropic of Capricorn from the winter solstice, and the sunshine is most inclined to the northern hemisphere, with the shortest day and the longest evening. After this day, the sun's rays gradually moved from the tropic of Capricorn to the north, and the days became longer day by day. On the winter solstice, the sun shines on the tropic of Capricorn, and the northern hemisphere has the shortest day and the longest night, so the winter solstice is also called the south solstice or "south solstice". Then gradually from the tropic of Capricorn to the north, the days in the northern hemisphere are getting longer day by day, and the southern hemisphere is just the opposite.
