New Delhi, March 4 -- A long drive through bumper-to-bumper holiday traffic turned into a viral love story after a man used a simple banner to ask fellow motorists for help reaching his girlfriend in time to propose.

The 26-year-old man, identified as Tan, drove 932 kilometres across China during the country's busiest travel period to surprise his girlfriend with a marriage proposal.

According to a report by the South China Morning Post, Tan is originally from Jiangxi province in central China but runs a business in Fujian province. In February, during the massive Spring Festival travel rush, he decided to drive to Guizhou in southwestern China, where his girlfriend had returned to celebrate the Chinese New Year with her family.
