As I said I'm pretty sure nothing is bold - it is just anti-aliasing. The fact that the problem is only occurring on Chinese Windows systems in 8.1.x very much suggests that this is a font problem (which is obviously universal in Win10).
Perhaps try a complete non included with Win Chinese font and see if the problem is seen then? Warmest Regards, Mark.
