this anti-matter concept contrast to physical attributes,
adopted by Paul Dirac, a British physicist in 1928,
four years later, evidences of anti-electron made waves in scientific community.
NASA put devices of anti-matter and ion in a giant balloon in the North Canada,
in order to search anti-particles in stratosphere 38 thousand meters upper air.
Two years between 1993 and 1994,
scientists found eight anti-protons in hundreds of thousands particles.
With the acquisition and evidence of anti-hydrogen atoms, scientists have unwavering will in studying and making good use of anti-matter.
At present, these studies mainly focus on the exploration of anti-particles.
And anti-matter is formed by anti-particle.
This, with the core concept of Yin-Yang fish, correspondence between anti-matter and matter,
are in line with the Yin-Yang thought illustrated in Yin-Yang fish.
If we define the white part of Yin-Yang fish as matter,
then the black part is anti-matter.
Then, correspondingly, white spots and black spots represent particles and anti-particles.
