His name is Lin Zheng, the most lonely driver on the WRC circuit.
Of the seven navigators, none could stay with him for half a season.
Until the woman showed up - carrying a hand-drawn road book left by her partner who was killed three years ago.
"He Zichen asked me to come," she said.
From Argentina to Finland, from gravel roads to icy mountain trails.
She couldn't tell the way, but she dared to sit in his passenger seat.
The most difficult corners are called blind corners - you cannot see the exit point before entering the corner.
He Zichen once said: "The best driver does not need a navigator to report the route, he only needs someone to accompany him."
This time, he didn't just have a name to run for.
There is another person worth trusting.
