When my wife got her US citizenship (OK, it was 40+ years ago), she had to verbally (and maybe (??) in some kind of a document) renounce any and all previous citizenships to the US official. Is this not still the case? However, I don't think she ever told the other country. If not the case today, does she still retain, even now, her previous citizenship?

Just keep the following in mind.
1. Depart/enter US on US passport
2. Enter/depart China with Canadian passport
3. Depart HK using same passport you entered HK with whether it be US or Canadian.
I also agree this would be the smoothest. You are lucky that you are going to HK before China since the airline would want to see your Chinese visa in your passport before allowing you on the plane if going directly to China.
