What does ruoku mean?

Ruojiu is a far-reaching word, which is often used to express the permanence and eternity of time. In Chinese, "if" means "like" and "long" means long time. If long can be used to describe the long history, such as "if the years are long", it can also express deep feelings, such as "if the lovesickness is long" in life. We often wish each other "if we are together for a long time" and express the hope that our friendship/love will last.

If it lasts for a long time, it can also be interpreted as "probability", which is a term in probability theory. In probability theory, if the time is long, it represents the possibility of an event. For example, the probability of a coin being thrown backwards is 1/2, that is, if it is long, it is 0.5. Ruojiu is also widely used in modern science and technology, such as machine learning, big data analysis and other fields. If used for a long time to predict the probability of future events.

In the Book of Changes, Ruojiu is interpreted as "divination in Fuxi's sixty-four hexagrams", which is a divination method. If the symbol of divination for a long time is "lightning meets the wind", it means that the two poles meet and heaven and earth intersect, which is not only the expression of nature, but also the mapping of human behavior. If the fortune teller divines for a long time, he can understand his present situation and future direction and guide himself to make more wise decisions.
