Tshwj xeeb tshaj li ntawm kev tsim cov cij nyom, uas yog lub hauv paus theem pib, cov casses dag coj los siv * ua ntej koom tes rau hauv tus qauv ntawm cov khoom ntawm cov khoom cuav, cov hlau muaj peev xwm ncav cuag tau 60 hli ntev tshaj cem nyom nyom, xws li cov khoom siv yog siv rau kev ncaws pob . Qhov ntev ntawm cov nyom yog nyob rau hauv txoj cai tus ntev lub zoo, tab sis qhov ntev ntawm cov nyom feem ntau siv nyob rau hauv football teb yog hais txog 30 hli.
Qhov thib ob yog hais txog cov khoom ua kom pom tseeb, nrog rau cov xim, qhov muag, qhov muag, thiab lub ntsej muag rau peb yam, kom muaj xim, qhov muag yuav tsum zoo, softness yuav tsum yog txhua yam cij nyom, cov casses dag tau muab tso rau hauv.
