Nin Maraykan ah ayaa sanadkii 2003 iibsaday Sixni hore loo isticmaalay kaasi oo laga siiyay $ 3 dollar keliya. Laakiin ninkaasi ayaa soo bandhigay sanadkii 2013 isagoo sheegay in lagu sameeyay dalka shiinaha wakhtigii ay xukumayeen boqortooyadi Sung Dynasty oo ah 1000 sano ka hor.
Markii uu sidaasi ku soo bandhigay ayuu qiimihiisu qaali noqday iyagoo kooxaha ururiya alaabooyinka wakhtiyada fog ee dib u iibiya iyo dadka hantida haystaa ay Sixnigaasi ku tartameen. Ninka ayaa ugu danbaystii ku iibiyay Sixingaasi lacag dhan $ 2.2 malyuun ( Laba milyan iyo laba boqol doller). Mudadaasi u dhaxaysay 2007 – 2013, oo muddo 6 sano ayuu dejiyay arinkaasi uu doonayay inuu ku helo lacag dhakhso ah. Mar danbe ayaa sheekda ninkan aad loo ogaaday laakiin waxa laga soo qaaday alaabo si caadi ah loo kala iibsaday.
