A report by SEMRUSH identifies that 29 pages have hreflang language mismatch issues.

Identified as languate "vi" hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link hidden link
I have checked your shared URL, and actually, from the WPML side, all is correct. The page has correct hreflang set.
It seems SEMRUSH error/message is false positive, and I suspect this happens because you have some English content on those pages, so SEMRUSH suspects it could be an EN page but hreflang is zh.
The best I can do is suggest making sure you have the correct language content on pages and mixing the language of content to avoid such reports. Of course, you can check further with SEMRUSH support for any advice, as we can provide SEO support / advices from our side.
I hope I was helpful. Don't hesitate to ask if you find any problem along the way, I'll gladly help you.
