The case came to light in June, when a resident surnamed Gu from Shizhai Village of Beiliu City in south China's Guangxi Zhuang Autonomous Region reported his grandfather's body was stolen from his grave.
Since body theft cases frequently occur in the region, Gu and other family members were guarding his grave in turns.
Still, they failed to prevent the theft of his corpse, state-run Xinhua news agency said.
In early July, police from Beiliu City apprehended a "grave robber" surnamed Zhong based on an investigation.
He also told the investigators that he sold the corpses to two officials from Gaozhou City and Huazhou City in Guangdong.
With the help of Guangdong police, the two suspects, surnamed He and Dong, were arrested.
Both were local officials in charge of funeral management reform.
They told police that they bought the corpses to finish government cremation quota.
China has a long tradition of ancestor worship, which usually requires families bury their relatives and construct a tomb.
Whether people are in favour of preserving farmland or upholding cultural tradition, the burial reform has aroused great controversy in rural regions.
In He and Dong's towns, local government has demanded a certain number of the dead should be cremated each month based on the total local population of the previous year.
