China people have a wide range of auspicious cultures, including animals, plants, colors, directions and architectural shapes. Besides, they also have various auspicious views on numbers.
In feng shui, numbers are considered to have special meanings. 2, 5, 6, 8, 9, 10 are auspicious numbers, 2 stands for ease, 5 stands for harmony of the five elements, 6 stands for wealth, 8 stands for wealth, 9 stands for longevity, and 10 stands for happiness and certainty. So "289" means "easy to get rich for a long time" or "prosperous business for a long time". "4" is an unlucky number in Feng Shui, especially in Cantonese, which sounds like "death", so "4" means death and extinction. For example, "744" is an unlucky number, which means "certain death" or "business failure".
People in China like even numbers in numbers and think they are paired to avoid loneliness. In odd numbers, "3" sounds like the word "alive" in Cantonese, but it is not considered particularly auspicious. However, some people just like to use "3". For example, there are two "3" in the number "7373", which means "certain survival". During this period, most numbers are attached with good or bad meanings, mostly from the pinyin of numbers and Chinese characters. If numbers are connected with Chinese characters, they are considered to have the meaning of Chinese characters. For example, the common "8" is regarded as the Chinese character "Fa", "9" is regarded as "Nine" and "6" is regarded as "Lu" and "You". The combination of these figures is the most popular because it conforms to the folk concept of getting rich. Such as "168", the Chinese homonym is "all the way"; "8888", the Chinese homonym is "hair hair"; "868", the Chinese homonym is "Mao and Mao" and so on. Therefore, in the folk, these license plate numbers, telephone numbers and house numbers are all considered as auspicious numbers, which can bring good luck to people.
Both human society and natural society have their own laws of development and change, and their processes will never change because of a certain number. Therefore, the reason why people attach importance to auspicious days is just a belief and a comfort to the desire for wealth. So for businessmen, there is no need to pursue this, and it is not worth spending tens of thousands of dollars to buy this comfort. Only by doing their business well can they really get rich. Of course, it is not bad to choose a meaningful day to open a shop for good luck.
