In the courtyards in the alleys of Beijing, the thousand-year mission of the mausoleum keepers in western Beijing is hidden. The copper rings on the red doors clasp the shadows, and the tiles on the eaves and corners serve to suppress evil shadows. The secret techniques of guarding the mausoleum are used to solve the strange things in the old house, and the dust-covered soul-soothing secrets of the imperial mausoleum are revealed. The world of fireworks and fire is the boundary between yin and yang.
