Daim ntawv ceeb toom

Qhov no tsuas yog ib qho yooj yim thiab yooj yim nrhiav txoj kev, uas yog siv los soj ntsuam cov khoom sai sai nrog cov purity / zoo. Cov txiaj ntsig siv zaum kawg tseem yuav tsum tau sim los ntawm cov cuab yeej kev sim ua haujlwm thiab ntxiv rau hauv mortar rau kev txheeb xyuas zaum kawg.
