烧纸 is a core ancestor-worship ritual: burning
纸钱 (spirit money),
纸衣服 (paper clothes), even paper iPhones to send goods to the afterlife. Traditionally done at
清明 (Tomb-Sweeping Day),
中元节 (Ghost Festival), and on the deceased's death anniversary; urban fire safety rules increasingly push people to do it at assigned
焚烧炉 (burning furnaces) instead of street corners.
