Can Zhouyi only ask one question every day?

Of course not. People have many things and ideas every day, which is actually one of the fundamental reasons why people have fate. People have many ideas, and naturally there may be many questions, but you can ask different questions, and more than one question. Six hexagrams is a kind of divination that can be used at any time. Plum blossoms can be used at any time according to the five elements or external needs. Other hexagrams, such as Daoism and Liu Ren, can also ask questions at any time (but traditionally there is only one game or one class per hour, which is another matter).

PS: Actually, what is more worth asking is that people have a destiny. The ancients also had a lot of research or works in this respect, such as "Four Disciplines from Fan". The Doctrine of the Mean says, "Honesty can be a prophet." ...
