The film raked in about 276.3 million yuan (about 40.2 million U.S. dollars) on its third day of screening, accounting for over 70 percent of the daily total.
The fantasy film follows the birth and growing up of Ne Zha, a mythical male figure created in ancient China who is widely known as the incarnation of a lotus. He is often depicted as a young hero standing on two flaming wheels in Chinese legends and literature such as the literary classic "Journey to the West."
It was followed by "Looking Up," a Chinese family drama, which grossed about 45.73 million yuan and had topped the Chinese mainland box office for eight straight days since its release on July 18.
"The Bravest," a China-produced film telling the story of firefighters, took third place with a daily box office revenue of about 31.4 million yuan in presale.
