Thank you Alexis and Kaushal. I might mislead you.

I am writing some short articles which includes a lot of Math formula. So I
include LaTeX command here and there like $A \subset B$. Most symbol
display OK when exporting to HTML. But the \subsetneqq not. Same article,
Html couldn't handle $\subsetneqq$ and display "Undefined control sequence
\subsetneqq" in final render. But display in PDF output correctly.

I guess this problem relates to MathJax and did a little googling  last day
but didn't find the solution.
