Then ceremonies describe a journey in which the Then Master (male or female) controls ghost soldiers travelling from the earth realm to the heaven realm, to offer items of worship and present their prayers for peace, for treating illnesses, good crops, a happy new year, etc.
The Then Master starts the journey by singing and plucking a tính lute. Depending on the worshipping purposes, Then masters arrange worship trips to pray to different native Gods.
Then masters use various items – such as a demon-expelling sword, a yin and yang rod, a bell, etc. – to perform ceremonies in the believer’s house, outdoors or at the Then alter of the Master’s house.
The Master wears ceremonial dress, sings in the language of their ethnic group, plays the tính lute, shakes rattle-bells and waves a fan. Some ceremonies are accompanied by a female dancing group. Then is always transmitted orally while its rituals are conducted, reflecting its succession between the generations, and Then Masters play a key role in passing on the related skills and know-how, with some conducting around 200 ceremonies a year.
The practice of Then worship has been inscribed on the UNESCO’S Representative List of the Intangible Cultural Heritage of Humanity since 2019.
