It is true if the trademark contains R.

According to the search on Baidu Encyclopedia, R is the abbreviation of REGISTER, which means registered trademark when used in trademarks. The circle R indicates "registered trademark", which means that the trademark has been applied for registration at the National Trademark Office and has been reviewed and approved by the Trademark Office to become a registered trademark. So if the Liu Zhiqiang bait trademark issued by Anhui carries an R, it is genuine.
