30m is, IIRC, the officiall PRC estimate for the whole Sino-Japanese War. This is probably exaggerated. I'd go for a number around 10m, but the estimates vary widely.

The actual number of Nanjing inhabitants at the time is hard to calculate, since the city was full of refugees. It may have been up to 1m, but I never saw the number of 20m anywhere.
Yes, I was confused about the figure as I was reading articles written in Japanese.
I meant to say that the population of Nanjing was 200,000 that time, while PRC claims that the figure for Nanjing Massacre was 300,000.
Probably no one knows.
It is hard to investigate unless researchers receive full corporation from Chinese government.
