You've landed in a discussion group for users of Mac versions of Word (not
your fault: it's a charming foible of Microsoft's web interface, which I
guess you used). Mac versions differ variously from PC versions. Although
several people here use both PCs and Macs and may give you an answer soon,
it's likely that more people in a PC group have experienced your specific
problem. Here's where all the groups are listed:

I suggest, though, that you give more information than you have here: for
example, how do you open the files; are they pre-existing files; do
characters other than Chinese characters show; what fonts are you using? --
things like that. Take your time to give as much information as you can.
Cheers,
Clive Huggan
