About 27 years old, very orthodox hairstyle, this kind of thing is bullshit. The original meaning refers to the movement of water caused by tides, and the extended meaning refers to the trend of fashion, which is a metaphor for the trend of social change or development. In power engineering, it refers to the distribution of voltage (including amplitude and phase angle), active power and reactive power in various parts of the power grid. 1: the development trend of things (the word "trend" is used to indicate the overall movement of sustainable development to distant goals that are not clear or only vaguely expressed).

Trend, which means the development trend of things, is now included in the Chinese Dictionary. Trends indicate the development of things. It represents the trend of stocks, futures and foreign exchange in the financial trading market, and is also the name of an anti-virus software company. It is also used for statistics.

Another explanation for this trend is to please power. I hope my answer will be helpful to your study. Please adopt it. Thank you.
