In home page the meta is english and contents is also english on the surface .but contents in home page is chinese from analysis result of whois domaintools ,i don't know why appear this question?
what do you mean "english on the surface" , if you post your website we can look into it. Sorry i cant understand your problem.Better if we can see your web site.
His website is in his signature. By looking at your website it is obviously China based. The domain is hosted in China, the domain was registered in China and you have Chinese text in the code. Perhaps that Chinese text is causing problems for the text browsers on whois pages.
Why would you have english meta tags when your site is in chinese? I would say, change it to chinese instead.
Better use meta tag related to the niche and also so better is use chineese also on it. Content is more important for SE than others like meta tag, title etc. So include title metatag tag both in
