1. At the end of the Eastern Han Dynasty: Zhang Jiao, with the ambition to help the world and save the people, went into seclusion in the mountains to practice in order to find a way to transcendence. One day, he accidentally discovered an ancient immortal cultivation book that exuded a mysterious atmosphere in a cave. The runes on the book were flickering and obscure. With his obsession and research spirit in cultivating immortals, Zhang Jiao spent several months studying day and night, and finally understood the unique method of cultivating immortals - "Taichu Hunyuan Gong". This method focuses on harmonizing yin and yang, conforming to heaven and earth, and focuses on the perception and application of the power of nature. This method not only greatly improved Zhang Jiao's own cultivation, but also provided him with a solid and unique theoretical and practical foundation for his future journey to the world of Red Mansions to cultivate immortality.
2. The world of Dream of Red Mansions: On the surface, the Jia Mansion is full of bells, cauldrons, food, and extraordinary wealth, but in fact, feudal ethics are like invisible shackles, firmly imprisoning everyone. Jia Baoyu and Lin Daiyu fell in love with each other, but due to the strict constraints of feudal ethics, the road to love was full of twists and turns. They cannot openly express their love and can only express it implicitly through poetry and eyes. For example, in the poetry club activities, Lin Daiyu expressed her feelings for Jia Baoyu through poems with delicate brushwork. Jia Baoyu also understood it, but could not express her feelings openly and openly. This repressed emotion is in sharp contrast to the equality and freedom pursued by Taiping Dao. It profoundly reveals the suppression of human nature by the decadent order of the Red Mansions world and lays the groundwork for the conflict in the story.
