A tenant in China who reported a foul smell and red liquid on her ceiling discovered that the marks came from her upstairs neighbor who had been dead for days.

A woman surnamed Liang in Liuzhou, south China's Guangxi Zhuang Autonomous Region, said she woke up to find a fishy smell in her room and dark red marks on her bed and chairs on Wednesday. When she traced these marks, she found they came from red liquid dripping from the ceiling.

"My ceiling was leaking with red liquid, which seemed like blood," she said.

When she called the police to investigate, they found that a man had fallen in his bedroom and had been dead for days.

The deceased was a 62-year-old man who lived alone and had no life-threatening diseases. His family had not seen him for more than 10 days.

At present, police are still investigating the specific time and cause of the death, adding that the possibility of murder cannot be ruled out for now.
