JD.com Gross Margin 20%, Pinduoduo 80%?

Not sure what statistical method they're using, but looking at the data chart, JD.com's gross margin is 20%, and net profit seems to have vanished. Pinduoduo's gross margin is 80%, and net profit is 20%.

Another way to put it is this: previously, we spent 50% on JD.com and 50% on Pinduoduo. But under the impact of economic downturn expectations, we've shifted to spending 80% on Pinduoduo and only 20% elsewhere. So other platforms are seeing data declines, while Pinduoduo is growing.

Pinduoduo's good times are our hard times
