I'd like to ask what the square pattern in the picture means (text reply is fine)

The swastika (pronounced "wan"), the swastika is the symbol of Buddha. The swastika is pronounced "Wan" by the Chinese and is also known as the Manji, or man ji by the Japanese. Its English name is Swastika, and in Sanskrit it is Srivatsa, which translates as "Muroku Chikara Shastra", and was formerly translated as "Auspicious Sea Cloud Phase", which means "Auspicious Collection". The swastika has the symbol of "auspiciousness" and "good fortune". The swastika has the meaning of "good fortune and luck".

Various forms of the swastika

The Buddhist swastika is a symbol of the universe, symbolizing the spinning machine that runs everything in the universe. There are many forms of the swastika, with the clockwise rotation being the swastika (right rotation), which represents absorbing energy from the universe, and the counterclockwise rotation being the swastika (left rotation), which represents giving out energy from the universe.

Hitler appropriated the symbol because the swastika has a long history of appearing throughout human society, and Hitler was only a few decades away. The Nazis stood with a reverse swastika using and black color as a symbol. And the swastika is usually the color of gold.

Various Western religions, including Christianity, and Buddhism have used the swastika symbol, just morphed it a bit is all.

Some archaeologists believe that the ancient Indo-European peoples were believers in God, and that they brought their beliefs with them everywhere as they migrated. The Mesopotamian and Ancient Greek swastikas may be the cultural imprint of the ancient Indo-European peoples. The Aryans who invaded India brought with them their faith, the original Brahminism, and also the swastika.

After Brahmanism came to an end, Shakyamuni Buddhism was spread in India and then in China. Along with the spread of Buddhism, the swastika was also widely used in China. It is worth pointing out that the swastika was already in use before Buddhism was introduced into China. It is worth pointing out that the swastika was used long before Buddhism came to China, much earlier than Buddhism. This means: the swastika is not the only symbol of Buddhism.

The appearance of the swastika in China is also a common phenomenon, dating back as far as 9,000 years ago to the Neolithic Pontusan culture. Swastikas have been unearthed in many parts of China, appearing very frequently and widely distributed in the remains of ancient times.
