"Auspicious everywhere" means that there are signs of auspicious everywhere. This word originated from China's ancient theory of "Five Elements" and belongs to a concept in Feng Shui. It means that any object or individual classified by the five elements can release the inner "dragon god" in a suitable environment, bringing good luck and blessings. Therefore, "Auspicious Quartet" is not only a praise for nature, but also represents people's expectations for a better future.

In the traditional culture of China, the "Auspicious Square" is often regarded as an auspicious pattern and totem, which is placed in palaces, castles, temples and other places, symbolizing the power and wealth of the emperor. In modern society, people often use auspicious square as an artistic decoration to increase the atmosphere and geomantic omen of the room.

On traditional festivals, weddings and other important occasions, people will also use the concept of "auspicious quartet" to express auspicious wishes. For example, during the Spring Festival, people will hang wealth cards in front of the "Auspicious Quartet" to pray for family safety, personal health and career success in the new year. At the wedding, people will also choose to use red wedding supplies with the pattern of "auspicious square", which means that this newly-married family will have a bright future.
