The animated film "Zhang Guo Lao" tells the fantastical story of Zhang Guo, a young man from Huaibei, who, by a twist of fate, consumes a mystical ginseng and cultivates immortality while riding a donkey backwards. He aids the world and saves lives, prays for rain to relieve droughts, and never forgets the kindness of his mentor and the bonds of family. Ultimately, he joins the Eight Immortals at the Pomegranate Feast on Tashan Mountain, transforming legend into a spiritual symbol that conveys the Chinese cultural ideal of "cultivating virtue to achieve immortality, and making good intentions come true."
