The site looks the same as this site zb.com which is an older domain compared to this zb.cn.
The zb.com domain has registrant contact and it looks like the owner is no leaving on China.

[email protected]But the zb.cn doesn't have registrant contact? There is a possibility that this domain is a fake one or the zb.com?
Anyone could register an expired domain but mostly they use this advantage to rank fast and possible can be scam.
Take old design of the zb.cn here
https://web.archive.org/web/20110112081455/http://zb.cn:80/ It's not a trading site before.
This one zb.com also for sale last 2017 and it seems that they registered the site last 2018 take a look at this old archived
https://web.archive.org/web/20170802170340/http://zb.com:80/I don't know which one is legit but both of them are newly registered last year(I mean these sites have both new owners).
For me, both of them are untrusted trading site so better to use well known exchanges than using these trading sites.
