"Dopamine" is a compound found in the body as a neurotransmitter and a precursor of other substances, including adrenaline. It influences various aspects of our bodies, from emotions to sleep and cognitive ability.

With the growing popularity of "dopamine dressing," a fashion that encourages people to wear clothes that boost their mood, "dopamine" has taken on the meaning of "the source of happiness." From colors to abstract concepts, almost anything can take on the prefix "dopamine" – dopamine scenic spots, dopamine diets, or even dopamine teachers.

The same can be said for many of China's rivers, lakes and coastal areas, which come in a variety of hues as vivid evidence of "Dopamine Earth."
