We don't have any data for China. None of their numbers are reliable, they make them up. This is one of the biggest issues in this pandemic: we don't know shit partly because China insist on lying...
Interesting support for your claims. Not saying they are wrong, but a classified US intelligence report doesn't really carry much weight either (link 1).
Link 2 is about the latest revision of the death toll in Wuhan. Now, you must think the current US death toll is totally accurate. Will you claim that the US makes things up when those figures are revised (which they will be) too?
We already have similar results from hospitals all over China. This is gravy.
Read the "smoking history" section of Table 1. https://www.nejm.org/doi/full/10.1056/NEJMoa2002032 and compare it to smoking rates in China over the past several decades.
