WHILE you’ll be hard pressed to find a Shanghai home with chestnuts roasting on an open fire this Christmas, there’ll be no shortage of people complaining about Jack Frost nipping at their noses over the coming days.

Though today will be sunny, with a low of 5 degrees Celsius and a high of 12, tomorrow will be decidedly cooler, with a high of just 8, forecasters said.

People with breathing problems might find it hard to have a wonderful Christmastime as a light haze is likely this morning, the bureau said.
