Who knows what the Japanese character is after one stroke

One-stroke problem.

Is it a simple math game, i.e., can a figure made up of curved segments on a plane be drawn in one stroke so that it is not repeated on each line segment? For example, the Chinese characters '日' and '中'中' can be drawn in one stroke, while '田' and '目'目' cannot. As early as the 18th century, the famous Swiss mathematician Euler.

I found the pattern of a stroke. According to Euler, a figure that can be drawn in one stroke must be a connected diagram.

A connected diagram means that all parts of a graph are always connected by edges, but not all connected diagrams can be drawn in one stroke. Whether a single stroke can be drawn is determined by the number of odd and even points in the picture. The mathematician Euler found the law of a stroke is:

Any diagram of connectivity composed of even points can be drawn in one stroke. You can start with any even point when drawing, and you will be able to finish the picture with this point as the end point. Any diagram with only two singularities (the rest are even) can be drawn in one stroke.

One singularity must be the starting point and the other singularity must be the end point. In other cases, the diagram cannot be drawn in one stroke. (There are even singularities divided by two to calculate how many strokes it takes to make this diagram.)

For example, in the attached drawing: (a) is the case of (1), so it can be drawn in one stroke; (b)(c)(d) does not meet the above two conditions and therefore cannot be drawn in one piece. Added:

Meaning of related terms Vertices and exponents: Let a plane graph be composed of a finite number of points and finite arcs, these points are called the vertices of the graph, and the number of arcs of the graph drawn from any vertex is called the exponent of the vertex. Odd Vertex:

Draw the middle horizontal, then the lower right corner, then the lower one, then the lower left corner, then the upper left corner, then the upper right corner, and then the upper right corner.

The Chinese characters '日' and '中'中' can be drawn in one stroke, while '田' and '目'目' cannot.

The Japanese character Yiyi is the word "horizontal", which can also be called "one painting". The word 日 is often used in Chinese characters to denote meanings such as sunshine, sun, or day. Judging from the shape of the Japanese character, the horizontal line represents the sun line, and the vertical line below represents the ground or the earth, and the whole Japanese character resembles the shape of the sun shining on the earth, which is very vivid.

Japanese characters are a very commonly used character in Chinese characters, and they are also very important characters. In daily life, people often need to use the word day to express things related to time and date, such as date, day of the week, or some words related to "daily life", such as "day after day", "daily life", and so on.

In addition to the common meaning of Japanese characters, it also has a very important place in Japanese culture. In Japan, the Japanese character refers to the national flag of Japan, also known as the "Nichisho Flag", which represents Japan's peace, prosperity, and strength. In addition, the first day of the Japanese New Year is also known as "Motori", a word that also contains the Japanese character.

In conclusion, Japanese characters are a very important and commonly used Chinese character, which is often used in daily life to express concepts such as time and date. In addition, it also plays an important role in Japanese culture, with important symbolic meanings in the national flag, New Year, etc. <>

Japanese characters add a stroke of Youby, old, Tian, Dian, 曱, 甴, Jia, Dan, 目, 白, Shen and so on.

1. Old (pinyin: jiù) is a Chinese character (commonly used character) in the first level of the general standard of Chinese. This character was first seen in the Shang Dynasty oracle bone inscription, the upper part of its ancient glyph resembles a bird, and the lower part is the sound next to the "mortar".

According to "Shuowen Jie Zi", the original meaning of "old" is the name of a bird, that is, "owl old", which belongs to the category of owls. The "old" that is commonly used in modern times as opposed to the new is a false meaning.

2. Tian (pinyin: tián) is a first-level character in the general standard of Chinese. The first text of this character was first seen in the Shang Dynasty oracle bone inscription and the Shang Dynasty Jin inscription, pictographs.

Its ancient character shape resembles a piece of farmland that is vertical and horizontal or ditches and is connected in all directions. The original meaning was the land on which crops were grown, and later extended to things related to agriculture.

3. Electricity, a commonly used word in Chinese, pronounced as diàn, was first seen in the oracle bone inscription, the ancient character "electricity" is a meaning word, the original meaning is lightning, and by extension, it is a kind of energy that exists in matter, and people use it to make electric lights shine, mechanical rotation, etc.; Derived from lightning to lightning-like lightning; From lightning to swiftness.

4. A, a commonly used Chinese character, pronounced jiǎ, was first seen in oracle bone inscriptions, and its original meaning refers to the seed shell worn after the seed germinates, which is extended to the first position in the order of the heavenly stem, and then extended to the first place.

5. Dan (pinyin: dàn) is a commonly used Chinese character, which was first seen in the Shang Dynasty oracle bone inscription. The ancient character of Dan is like the sun rising from the ground, which originally means dawn, that is, the meaning of "morning" and "dawn", and thus derives the meaning of "light", "day", "the beginning of the day", etc., and refers to a certain day.

It also refers to the role of a woman in traditional opera, that is, the role of Danjiao.
