These celebrations can last from a day up to the entire week , and the New Year is filled with people in the streets trying to make as much noise as possible using firecrackers, drums, bells, gongs, and anything they can think of to ward off evil spirits. This parade will also include different masks, and dancers hidden under the guise of what is known as the Mua Lan or Lion Dancing. The Lan is an animal between a lion and a dragon, and is the symbol of strength in the Vietnamese culture that is used to scare away evil spirits.
