Religious "ghosts" pop in and out of the New York Times' coverage of the funeral of Wenjian Liu, one of two police officers killed by ambush in New York on Dec. 20. Although Chinese people have lived in New York since at least the mid-18th century, the Times seems puzzled on how and how much to add.

Some of the reporting reads almost like one of those travelogues from a couple of generations ago, head-scratching over "those" peoples' odd customs. Here's some stuff from the advance story -- which, yes, uses the word "customs":

Officer Liu will be honored at a funeral home with Buddhist monks praying. Mourners will burn ceremonial paper money and objects in front of his photograph — riches, according to Chinese custom, for the afterlife.

Later, the Times adds some dabs with the help of Hugh Mo, a Chinese former deputy police commissioner.

At a traditional Chinese funeral, mourners wail and sob throughout. Some fall prostrate on the ground. Many attendees pay their respects and leave, rather than staying for the full service. Eulogies are not usually given.

“The Catholic funeral is a celebration,” Mr. Mo said. “The person is going to a better place, the person is going to be seeing St. Peter. A Chinese funeral is not a celebration, it is a mourning.”

While Officer Ramos’s wife appeared “courageous and dignified in the face of such great loss,” containing her emotions during her husband’s funeral on Saturday, Mr. Mo said, “if you look at a typical Chinese funeral, that is not the way to behave."

Right. It's an exotic Chinese custom to wail and show expansive grief at a funeral. No other ethnic groups ever do that.
