A week ago before the museum opened, a couple was found dead in their apartment in Jiaxing city of East China's Zhejiang province by their migrant son who works in Shanghai municipality, which ignited online debate in the country, Qianjiang Evening News said.

The father was thought to have died after an accident ten days ago, while the mother, who had Alzheimer's Disease, was thought to have died of dehydration and hunger one or two days ago before being found, the report said based on preliminary investigation.

Official statistics showed that China has at least 62 million empty-nest elders, one third of the total aging population.

"I hope the museum can encourage public to respect and take good care of elders. Time cannot wait us to love our parents," Wang Rui said.
