Following numbers from a filing in a chinese company while sitting in Europe isn't the DD I'm interested in nor does it mean anything. I'm talking about DD on site, checking with customers, suppliers, checking SAIC filings, checking bank accounts and so on and so forth. I don't know how many chinese stocks you have followed in the last few years but if you think that a 10Q filing can tell you in a meaningful way if the numbers are for real, then I guess you haven't followed the sector a lot.
That doesn't mean RD doesn't do good work. It's just not the stuff I'm looking for if one talks about DD in a chinese company. That's all.
