This also applies to the current geomantic omen. Many people need geomantic omen to make corresponding judgments when looking at foundations and buildings. Relatively speaking, there is still a certain superstition, but it also has a certain credibility, because it is also handed down from historical traditions.
Of course, for Zuo Qinglong and You Baihu, you may use them to make some jokes at ordinary times, but basically few people understand their meaning, because its meaning is complicated and needs to involve some Taoist thoughts and Feng Shui knowledge, which many people don't really understand. So in normal times, we can also have a certain understanding of these geomantic omen, which can better help us understand some problems in life and play a very good role in increasing our knowledge.
In a word, the phrase "Suzaku left a green dragon and right a white tiger, Xuanwu queen" is mainly used in Taoism and geomantic omen, so relatively speaking, the average person knows less, which is normal. Of course, we can also read related books, which can help us learn more about Feng Shui and improve our cultural literacy.
