The event features stalls selling products and toys for the traditional festival, cultural and art performances, and folk games.
A highlight of the festival includes a contest of arranging mid-autumn offering trays and a procession of lanterns.
Speaking at the opening ceremony, Vice Chairman of the People’s Committee of Hoan Kiem district, which organises the festival, Nguyen Quoc Hoan said it has become a traditional cultural charm of the district, particularly since the Old Quarter was recognised as a national cultural heritage.
The event lasts until September 10.
