Tianming Divination Master

My name is Zhang Yuanqing. My grandfather said that I will not live to be eighteen. When he said this, I had just used his mahogany sword to smash the vat in which I used to pickle pickles. The old man was so distressed that he gnashed his teeth and picked up his bench and chased me for three streets. Until the night of my eighteenth birthday, I saw with my own eyes that my grandfather turned into a white light and collided with a group of black fog. The next day, a neighbor found his "body" in the river. The funeral was sloppy, and I knelt in front of the mourning hall, flipping through the suicide note he left me. There are only eight words on it: "Twenty-four years old, Li Banner, surname Zhang." Six years later it was my 24th birthday. Carrying the shabby canvas bag left by my grandfather, which contained an abacus with a broken tooth, a box of dark red cinnabar, and a wolf-hair pen with a polished barrel, I walked into the urban village of this city. At the end of the alley, I opened the banner with the "Twenty-Four Hexagrams" written on it and hung a dim lantern. Waiting for a customer named Zhang. Eleven o'clock at night. A woman stopped in front of my stall. "Excuse me, is this the 'twenty-four hexagrams'?" "My surname is Zhang," "My name is Zhang Wanqing. This novel and its characters are purely fictitious.
