Before 1949, Gelo marriage customs were feudal, with matches made by parents at childhood, regardless of the desires of the children involved. As Gelos were so few and so scattered, marriages were usually made among cousins. To celebrate the marriage, the bride would walk with her relatives, carrying an umbrella, to the groom's home, where they would live apart from their parents.

While funeral customs in most Gelo communities are the same as in Han areas, singing and dancing still marks funerals in a few places, such as Zunyi and Renhuai counties in Guizhou. There, mourners dance in groups of three, one playing a lusheng (reed pipe), one beating a bamboo pole, the third brandishing a sword, and all singing as they dance. In other areas, mourners sing in front of the coffin; family members of the deceased serve wine in gratitude to them. In some places, a shaman who chooses the time and place of burial recites scriptures at the grave. Animal sacrifice usually accompanies the burial. Trees, rather than stones, mark the grave.

Gelo folk literature consists of poetry, stories and proverbs. Poems are of three, five or seven-character lines. Most Gelo folk tales eulogize the intelligence, honesty, diligence and bravery of the Gelo people, and satirize the upper classes. Typical are "The Brave Girl" and "Deaf Elder Brother and Blind Younger Brother Stealing Sheep." Gelo dances are simple and graceful, accompanied by the erhu, horizontal xiao, suona, gong, drum and other string and wind instruments.

"Flower Dragon" and "Bamboo-Strip Egg" are two favorite Gelo games. "Flower Dragon," in fact, is a ball of woven bamboo, a little larger than a ping-pong ball. Inside are bits of broken porcelain, coins and sandstones. The game, especially popular in Zunyi and Renhuai, is played by groups of pairs on hillsides. "Bamboo-Strip Egg" is also a ball, larger and stuffed with rice straw. Two teams of three or five throw and kick the ball, avoiding contact except with the hands or feet.

Most Gelo festivals echo Han traditions, but some practices differ. At Spring Festival-- the Lunar New Year -- Gelos offer a huge rice cake to their ancestors and after it is made, it remains untouched for three days. In Guizhou's Anshun, Puding and Zhenning, Gelo communities also celebrate the sixth day of the sixth lunar month by sacrificing chickens and preparing wine to bless the rice crop already in the fields.

The sixth day of the seventh lunar month marks the second most important event of the year, a festival of ancestor worship in Wozi and Gaoyang villages of Puding County. Oxen, pigs and sheep are slaughtered for ritual sacrifices to ancestors.

On the first day of the tenth lunar month, Gelos give their oxen a day of rest. This is the day of the Ox King Buddha, and in some communities on this day oxen are honored and fed special rice cakes.

Prior to liberation, Gelos had a number of distinctive taboos. During Spring Festival, for example, they did not allow themselves to sweep floors, carry water, cook food, clean houses, plough, ride horses or pour water from their houses. In some areas on other holidays, Gelos would not transplant rice or build houses if they heard thunder.
