"The Blessing Master in the Alley" is a story of guardianship intertwined with spiritual cultivation and the fireworks of the city. Veteran Lao Yang appears to be an ordinary community security guard, but in fact he is a monk hiding in the bustling city. For fifteen years, he used the security pavilion as an eye and hand-painted the word "" as a talisman to purify evil spirits, appease the souls of the dead, and silently guard the sleep of more than 400 residents of Qingheyuan in the middle of the night. When the shadow of modern cities quietly grows, this silent night watchman will once again turn his pen into a sword, drawing a warm boundary for ordinary people's lives under the dim street lights.
