Why do people in The Longest Day in Chang 'an call Xuanzong a "saint"? What are the allusions?

The Longest Day in Chang 'an is a recently hit TV series. Some people wonder why Tang Xuanzong was called a "saint". Influenced by Taoist thought, the saints here deliberately changed the title of "supreme" in TV dramas, so that Xuanzong of the Tang Dynasty was called "saint".

Let's talk about Li Longji, Emperor Xuanzong of Tang Dynasty. He belongs to the emperor and is the son of heaven. According to the historical data, Book Rites of the Six Dynasties of Tang Dynasty, Book Rites of Tang Dynasty, the fourth volume records: "All foreigners outside the Xia Dynasty are called' emperors', courtiers are called' supreme' inside and outside, courtiers call themselves' me' and courtiers call themselves' Your Majesty'. Today's emperor, people of all ethnic groups in China should be called "Emperor", courtiers should be called "Supreme", emperors should call themselves "I", and officials should call themselves "Your Majesty" when facing the emperor.

There is also a certain basis for directors and screenwriters in TV dramas to let others call the son of heaven a "saint". The Tang Dynasty was dominated by the Li family, and the name of Laozi, the ancestor of Taoism, was "Li Er", which happened to be the same surname. In addition, advocating Taoism can reveal the authenticity, so the Tang Dynasty took Taoism as the state religion, respected Taoism and suppressed Buddhism, and took Laozi as its ancestor. Laozi belongs to a saint, so the emperor of the dynasty can also be called a "saint".

At that time, the whole country believed in Taoism, and Li Bai's title of "fallen immortal" was influenced by Taoism. Therefore, Emperor Xuanzong of the Tang Dynasty allowed him to "call the world out of the boat and call himself Brewmaster". Tang Xuanzong was especially fascinated by Taoist thought. He once said that he dreamed of Laozi, and then he wrote an imperial note to the Tao Te Ching to express his admiration for Laozi. In the original works of Tao Te Ching, the most ideal ruler in Lao Tzu's mind is a saint. Most courtiers also believed in Taoist Puritans, calling Tang Xuanzong a "saint" at will, and Tang Xuanzong was happy to be called like this.

Therefore, it is reasonable to call Xuanzong "holy", "supreme" and "son of heaven". It's also good to learn history while watching TV plays.
