Ludup, known by the lay name Rinchen Goedoe, was enrolled at Kirti Monastery at a very young age and hailed from a Samsang family in village number four of Meruma township in Ngaba (Chinese: Aba), Sichuan Province.

In June 2020, Lundup, who was 54 years old, was arbitrarily arrested in Ngaba (Chinese: Aba) County in Ngaba Tibetan and Qiang Autonomous Prefecture, Sichuan Province, 12 years after he carried out a protest in front of Kirti Monastery in Ngaba County on 16 March 2008. The authorities neither informed his family where and which court oversaw his trial, nor gave any notice about what he was charged with.

In February, Ludup was released from prison with injuries after being made to carry out forced labour during his three-and-a-half-year prison sentence. Ludup was under police watch and without access to medical care after release from prison.
