These are three correct numbers.

The numbers 7, 8, 3 and 9 can represent when you enter Huatang by horse.

This is based on the correspondence of five lines of gossip in China's ancient fortune telling. Among them, beating a horse stands for the number 7, because in ancient China, seven fairies rode down to earth on a rainbow of seven colors, and the image of the rainbow was similar to that of a horse. Going up the mountain represents the number 8, because the shape of the mountain character is similar to 8, and entering Huatang represents the number 3, because Huatang has three horizontal characters, which can represent the number 3. Finally, the word Tang Can can also be interpreted as 9, because in China culture, 9 stands for perfection, auspiciousness and wealth.

The relevant knowledge of entering Huatang immediately is as follows:

1. Beating horses is an ancient custom, which is related to riding horses. In ancient times, horses were one of the main means of transportation, and riding horses represented freedom, power and glory. Therefore, beating a horse can be understood as driving a horse, which means a free and brave mental state.

2. Going up the mountain represents loftiness, sacredness and self-cultivation. In the ancient culture of China, the mountain was the residence of immortals and saints, and the place of cultivation and enlightenment. Therefore, going up the mountain can be understood as a symbol of pursuing lofty realm and practicing enlightenment.

Entering Huatang means entering a luxurious palace or temple, representing power and glory. In ancient times, Huatang was the residence of emperors and nobles, representing authority and dignity. So entering Huatang can be understood as a symbol of gaining power and glory.

Entering Huatang can be immediately understood as a symbol of pursuing freedom, lofty realm and power. This expression has a profound influence on China culture and is widely used in literature, art, philosophy and other fields. It represents a positive and enterprising mental state, and also represents the pursuit of power and glory.

In modern society, we can still see the influence of the expression "Go to Huatang at once". For example, in some novels, movies, TV plays and other literary and artistic works, it is often the protagonist who gets success and honor after going through hardships, and the protagonist in these works is often described as the image of hitting the mountain and entering han tang immediately.
