A strange tavern nestled deep in the mountains and forests, run by a young tavern keeper. Each cup holds a different kind of liquor, accompanied by stories of painful pasts that people would rather forget. Along the river of history, there are always things that grow tiresome to hear, as well as others that leave us reminiscing endlessly. The creaking sound of the door opening brings not only a person, but also a story. Li Shimin: "Tavern keeper! Bring me two pots of Jiannanchun!" Lin Su: "I don't have Jiannanchun here, but I do have a drink called Xuanwu Gate. Would you like a cup?"
