To prepare for the ceremony and Hung Kings Festival 2013, the Hung Temple historical relic has completed the upgrading of car parks, working houses, reception houses, Lac Long Quan Temple, and pavements.

UNESCO recognized Vietnam's Hung King worship ritual, centred in Phu Tho province, as part of the world's intangible cultural heritage.

For generations, the Vietnamese have considered the Hung Kings the founders of the country and the fathers of the nation.

Every year, in the third month of the lunar calendar, Vietnamese people from all over the world gather in Phu Tho to visit the Hung Kings Temple, pray for good weather and peace, and show their gratitude to the ancestors.

According to Assoc. Prof. Truong Quoc Binh of the Vietnam Art and Culture Institute, over thousands of years, ancestor worship rituals have become a national tradition.
