"The part above that line has been exposed for 600 years, while the part below it has just done so for 50 years, since when the Buddha sculptures right in front of the walls were destroyed on that fateful day," she said.
Today, those sculptures can only be viewed in the black-and-white pictures taken by British reporter Angela Latham, Morrison's contemporary who photographed the temple in 1937 and had the pictures published in the Illustrated London News that same year.
Wu, in the final years of his life, suffered from Alzheimer's disease and handed the keys to Fahai's main hall to Ding. He died in the mid 1970s aged 74. "He never left the temple," Ding says.
Before his death, Wu, who had been an antiques dealer for years before a series of misfortunes brought him to Fahai, left a will in which he requested to be buried near the temple. The family obliged.
