\u00a0 \u00a0 \u00a0 \u00a0After keeping koi for more than ten years, when the sunlight penetrates through the clear water and reflects the colorful scales of koi in the morning, I finally understand: the so-called way of keeping koi is just a patient answer sheet delivered by human beings to nature. These living works of art, which have been swimming for thousands of years, teach us the balance of ecology with the opening and closing of their gills and the meaning of perseverance with the swinging of their fins. This specification transforms the rigorous technical parameters into a touchable poem in the water, wishing that every reader can grasp the key of scientific breeding and also guard the gentle bond across species.<\/span><\/p>\n

But please remember that the numbers in the manual are only the starting point. What really determines the success or failure of koi farming is the concentration of your eyes when you observe the water quality changes day after day, and your persistence when you deal with fish diseases late at night in an emergency. When your koi leaps out of the water in the morning light, what glitters in the splashing water droplets is not only the micro-awning of science, but also the crystallization of emotions.
