What do you mean, the lotus blooms before the summer solstice?

The solstice of summer has not yet arrived, and the lotus is in full bloom.

The lotus is in full bloom before the summer solstice, which means the lotus is in full bloom before the summer solstice. It implies that I hope that the person I am waiting for can also arrive ahead of time, expressing my expectation and tenderness for the person I am thinking about.

The summer solstice is the 10 of the 24 solar terms. At noon, the sun longitude is 90 degrees, and the solar calendar is June 2 1 to 22. The solstice in summer is the turning point of the sun's northward movement. After the summer solstice, the direct point of the sun began to move south from the Tropic of Cancer.
