Tangshan and Urumqi were the first to see the sunrise.

Reason:

The earth rotates from west to east, and the vernal equinox and autumnal equinox are equal in length, and the sunrise is first seen in the east. Autumnal equinox to vernal equinox, southern hemisphere; At the same longitude, the greater the south latitude, the earlier the sunrise will be seen. There is no night in Antarctica. Equinox to autumnal equinox, northern hemisphere; At the same longitude, the greater the north latitude, the sooner you can see the sunrise. There is no night in the Arctic. According to the height of the sun, make the terminator line, and you can judge.

Day length (latitude) and longitude difference are two major factors that determine the morning and evening of sunrise:

1. Longitude: The farther east, the earlier you see the sunrise;

2. The days are long; The longer the day, the earlier the sunrise;

3. Terrain: The terrain is high and the sunrise is early.
