China has a tradition dating back thousands of years of ancestor worship, which usually requires families to bury their relatives and construct a tomb.
But in recent years local governments across the country have demolished tombs as part of a national campaign encouraging cremation, in an attempt to save on limited land resources.
Government officials in Anqing, a city in the eastern province of Anhui, ordered that all locals who die after June 1 should be cremated, the Beijing News daily reported.
It said government officials began forcibly to confiscate coffins from locals in May, which "had a huge psychological impact" on them.

But it added a note of scepticism, saying that the reasons for the suicides were "complex" despite the family claims.
One 91-year-old woman named Wu Zhengde hanged herself on May 5 after learning of the new regulations, the report said.
Another woman, Zheng Shifang, 83, killed herself after officials sawed her coffin in two in front of her. A 68-year-old woman killed herself by jumping into a well, while others drank poison.
"China is big, death and sickness amongst the elderly is normal," the report quoted a local official as saying.
The paper quoted Beijing-based lawyer Zheng Daoli as saying the seizures were illegal because coffins were the property of their owners.
Elsewhere in China local officials have launched massive campaigns to "flatten graves" to create land for farming and development.
