Just look for a globe (the globe is not good, it's too thick) or a map (a thinner atlas will do, especially for provinces). They are:

114e 35n Zhongmu (the original question is not accurate, if you choose Zhengzhou or Kaifeng, you must have finer coordinates) 109e 34n Xi'an.

It's very tiring, some of them should have a decimal point.

Different longitude regions use different times, where does it come from at 12 o'clock at noon? It's twelve o'clock at noon at your house, and it's still the middle of the night in the United States. Upstairs won't teach you stupid and leak people.
At the time of the spring and autumn equinoxes, the days are the same in all regions of the world, but according to the longitude, the east longitude of place A is 110°, and the east longitude of place B is 115°, so the sunrise of place A is 20 minutes earlier than that of place B, and the sunset is 20 minutes earlier than that of place B.
On the summer solstice, the latitude of place A is higher than that of place B, and its sunrise time is earlier than that of place B, so it exceeds the original stall for 20 minutes, set to x, and the sunset delay is y, with x+y=56So when y=48, x=56-48=8<20, thus excluding answer d.
To have both A and B sunset at the same time, unless the latitude and longitude of A are higher than those of B, but the fact is that the latitude is 5° lower, answer B is excluded.
If x=y=28, then the longitude of the two places must be equal, so answer A is excluded.
To sum up, choose C.

Tell you this, can you understand it? Regardless of the location, the angle between the position of the sun and the ground level reaches its maximum at 12 o'clock in the afternoon. That is, twelve o'clock at noon is the middle point of the day. In this way, isn't the answer out of the silver leak?
