Before answering this question, let us first consider what calligraphy is. Nowadays, in addition to hard-pen calligraphy, calligraphy is often just a kind of art, a taste, and a hobby for us.
The cleaning guy who writes calligraphy with a water gun:
The inventor of water gun calligraphy is a cleaning guy at the China Academy of Fine Arts: Xie Zhongci. He is not a student of the Academy of Fine Arts himself. He just stayed at the Academy of Fine Arts for a long time and has a hobby of calligraphy. One day, while he was working, he discovered that a high-pressure water gun had hit the surface of the ceramic tiles, and marks of varying thicknesses similar to those of a brush appeared on the surface of the ceramic tiles. He had a sudden idea and planned to use a high-pressure water gun to write calligraphy. He mixed the ink into the water, but the effect was not very good. After many attempts, he invented the calligraphy method of applying ink first and then using a high-pressure water gun: high-pressure water gun calligraphy. The lines written in this way are smoother and rounder. It even feels like a monument.
The cleaning lady is just an ordinary worker. Just because he had worked at the China Academy of Art for a long time, he became interested in calligraphy, and his interest drove him to write calligraphy with water gun. I suddenly felt that this is the meaning of art. Give us the enjoyment of beauty. Bring us happiness.
The cleaning brother is creating:
This reminds me of last year. A video of a professor's ink-shooting calligraphy. No matter who was at that time, they were all impressed by the great professor's imagination. Someone actually used the injection fluid usually used for injections to create calligraphy! At this time, everyone was just watching the fun, but people in the circle did not agree. They thought using a syringe to write calligraphy was pure nonsense. But at the time, I felt that as long as I liked it, I could do whatever I wanted. But later on, he relied on this kind of maverick behavior to become famous and make a lot of money. This is really unacceptable.
Water gun calligraphy display:
High-pressure water gun display of calligraphy, this must be calligraphy. He can fully meet the meaning of calligraphy to people: self-cultivation, a sense of accomplishment and happiness.
In summary, art originates from life and is higher than life. Art is naturally not achieved by sensationalism. Tools for one's own due benefits. So I think the words written by the cleaning lady with a water gun are real calligraphy and even real art. The criterion for judging whether it is calligraphy is not whether the writing is good or not, but whether it is done with care and effort, because art is the beautiful fruit of hobbies and hard work.
