Friend recommended Wuling sales data: How to extract the real insights

Last week, while staking out the Shenzhen Auto Show, a friend working in the automotive supply chain insisted on showing me Wuling's July sales brief. He said, "120k units sold, over 70k new energy vehicles—calculate the penetration rate." At first, I didn't pay much attention; after all, as a reporter, the last thing you want is to rely on numbers companies release themselves. But later, I spent an afternoon breaking down that pile of data from start to finish and found it was actually quite interesting.
