Shanghai's 54 cemeteries and columbariums received 392,100 tomb sweepers on Tuesday, the day of dongzhi, or Winter Solstice, about the same number as on the corresponding day last year.

They brought an extra 79,700 vehicles onto the streets, according to the Shanghai Civil Affairs Bureau.

Winter Solstice, like Qingming Festival, is a time when Chinese people pay respects to their ancestors. It falls on December 21 this year.
