A weekend before the Mid-Autumn Festival, my girlfriend and I drove to Mentougou, a suburb of Beijing. We hiked all the way to the peak of Ling Mountain at 2303 meters. It is said that this is the highest peak in Beijing. And it was also the highest mountain I had ever climbed so far. We knew that this would be our last trip this year with a car. So the whole journey was filled with complex feelings. Selling the car was the worst scenario when I started the business last year, or rather, when I first bought the car. The original words were: if the company runs out of money, then sell the car; if that doesn't work, sell the house. Never did I expect that this joke has become reality如今. From buying a car to selling it, it was less than a year.
