The traditional ritual embodies prayers for good health, favourable weather, and bumper harvests, while also providing a chance for locals to pay tribute to those who rendered service to the community.

At dawn, local residents prepare a cow, a pig, three chickens, and items for the worship ceremony, held 4 km from the commune centre. As the ritual begins, they gather around the stone pillar. The head of the Mua clan leads the ceremony, inviting the stone deity to accept the offerings and bless the community with prosperity and good fortune.

According to elders, during the resistance war against French colonialists, Hang Chu commune was home to Mua Chong Lau, the most influential and affluent leader in the region. With his prestige, the man united local Mong residents in supporting the Viet Minh and the resistance movement.

Learning about Lau’s activities, the French colonialism sent troops to Hang Chu, establishing the La-hu-van garrison to suppress locals. Lau was arrested and imprisoned there. However, he secretly encouraged his family and locals to help him escape and reconnect with the revolutionary forces. Before making his escape, he prayed to the stone pillar: "For the revolution, for the resistance war— the sacred stone pillar, grant me your protection so I may flee successfully."

After Lau passed away, locals held a ritual to worship both the stone pillar and Lau at the start of each new year, praying for good health, favourable weather, and bountiful harvests. The ceremony reflects their reverence and gratitude toward those who contributed to the community, while also providing an opportunity for residents to relax and enjoy spring festivities after a year of hard work.
