The Qingming Festival sees a combination of sadness and happiness.
The Qingming Festival started from the Zhou Dynasty, and has a history of over 2,500 years. [...] In the year 732, Emperor Xuanzong of the Tang Dynasty, declared that respect could only be paid formally at ancestors' graves on the first day of the Qingming solar term.

Some people carry willow branches with them on Qingming, or put willow branches on their gates and/or front doors. They think that willow branches help ward off the evil ghosts that wander on Qingming.
Also, they offer uptraditional Chinese foods, liquor or "ghost money" or anything else that they think their ancestors might desire or need in the afterlife. [...] They could include joss paper versions of cars, air conditioners [...] These items get printed on joss paper and burned (just as is done with ghost money), thus sending them on to the next world.
Unlike most traditional observances which are determined by the lunar calendar, Qingming falls two weeks after the vernal equinox, April 4-6 on the Gregorian calendar.
