The Lang Pang A (thanksgiving) Festival consists of two parts: the ritual part and the festive part, with the purpose of thanking heaven and earth, genies, and ancestors for people's health and good crops. In the ritual part performed at home and in the forest, people offer pork, chicken, duck meat, rice wine, and rice. The shaman performs the ritual; invites ancestors and gods to attend the ceremony; enjoy offerings and bless people to always be healthy. In the festive part, there are dances close to daily life and imbued with ethnic identity, reflecting production activities, wishing the gods to bless favourable weather, lush trees, peaceful villages, and prosperous and happy clans.

The festival is a unique cultural activity full of humanity of the La Ha ethnic group, helping to improve spiritual life, increase faith and will to live for everyone in the face of illnesses, challenges and difficulties in life, teach people to know how to do good and avoid bad, and how to behave, and promote national solidarity. In addition, the re-enactment of the festival contributes to building cultural tourism products, creating a highlight to attract both domestic and foreign visitors to Thuan Chau district.

This is an activity within Sub-project 1 under Project 9 on restoring and preserving musical instruments, costumes, typical traditional crafts, and traditional festivals of ethnic minorities under the National Target Programme on socio-economic development in ethnic minority-inhabited and mountainous areas for the 2021 – 2030 period.
