In the 16th year of Qianlong's reign, Huizhou's Shenji Tea Company was in dire straits - thirty tons of Lapsang Souchong were impounded for "forgery of tea introduction." The helmsman, Shen Yanzhi, had to deal with Mitsui & Co.'S commercial crackdown and raise the three thousand taels of gifts from Lu Qingyuan, a Miss Lu family. When he was desperate, he met Takashima Tonxiang, a Japanese Yi scholar. The prediction of the hexagram "Dong Cao fierce" pointed out the crux of the crisis, and also guided him to find the "southeast water nobleman".
Lu Qingyuan came with the real tea book, but he was involved in the whirlpool of salt merchants' monopoly and official corruption. His determination to cling to evidence of crime on the edge of the cliff made the two deeply in love. From the tea farmer uprising in Wuyi Mountain to the pirate ship robberies in Vladivostok, Gaodao's Kan hexagram "seeks small gains", Yi hexagram "lives endlessly", and Tai hexagram "small things go to big things", have illuminated the way for them to break through the situation time and time again.
When the official ships of the Suzhou Zhizao Mansion and the tea recipes of European foreign merchants came one after another, Shen Yanzhi and Lu Qingyuan used "integrity as the tea, Yi Dao as the guide". In the ups and downs of the shopping mall and the court game, they not only protected the foundation of the century-old tea business, but also wrote a Jiangnan legend of "the hexagram determines the fate, and the friendship is passed down to the world".
