That original posters plane bears little resemblance to the YF-23 other than a maybe a few basic angles. The inlets are closer to the F-22, as is twin the vertical tail and nose chin. The YF-23 had no redundant flight control surfaces, the Chinese plane has several. Neither the YF-23 or the F-22 have front canards, for good reasons safety and engineering wise.
Sorry but they are alike only in the fact that they both fly (oh wait perhaps not) and have a twin engine twin tail arrangement.
