What is the allusion of Wang Wen Meng Xiong and what does it mean?

The legend of "King Monk Xiong Fei" has been circulated for thousands of years, which is described in detail in Legend of the Gods. Zhou Wenwang ordered the construction of an altar for sacrifice and named it "Lingtai". After the completion, the king and ministers of Japan held a banquet to celebrate and went to bed on the platform at night. The book describes: "King Wen and all the civil servants hosted a banquet on the platform, and both the monarch and the minister were happy." . After the banquet, he rested under the stage and King Wen slept on the embroidered couch. It was the middle of the night, just as I was dreaming, I suddenly saw a white-fronted tiger in the southeast, with wings under its wings, rushing towards the tent. King Wen called for help, only to hear a loud noise behind the stage, and the flames were soaring. King Wen woke up, sweating with fear. King Wen listened to the night, thought about the good or bad of this dream, and waited until dawn to discuss it. There is a poem to prove it: "The monarch and the minister * * * like to pass the cup and dream of flying bear at night; Since then, the dragons and tigers have met, and Xiqiao has won the column. " The next day, a doctor named Sanyisheng had a dream for King Arvin, and said all his life, "In the past, Emperor Gaozong of Shang Dynasty had a dream of flying bear, which is legendary. Today, the Lord dreams that the tiger has wings and is a bear. " This "flying bear" is Jiang Ziya. Jiang Ziya, surnamed Jiang, flying bear. At that time, Jiang Ziya was: "The short pole and the long line guard the stream, and this institution knows it well; Why fish in troubled waters? " Jiang Ziya fished with a straight hook and did not listen to the woodcutter's persuasion: "I would rather take it straight than beg;" Not for the scale, just for the prince. "From this perspective, tigers and bears were auspicious things in ancient times. In the Romance of the Three Kingdoms, Dong Zhuo's elite troops were called "Flying Bear Army". But I don't know why, until now, the tiger is still strong, but the bear is declining day by day, especially with the word "dog", it has become a worse bear; Is the hero or the "bear" pulled out for a walk? This bear became the antonym of "hero". The stock market also bullies bears. When the stock market is good, it is a "bull market" and the stock market crash is a "bear market". Even the swearing words are: you bear! Anything with the word "bear" is derogatory. Fortunately, the idiom "a tiger's back and a bear's waist" is of positive significance.
