1. Kev ceev faj txog kev khaws cia: Khaws cia rau hauv qhov chaw txias thiab muaj cua nkag. Khaws cia kom deb ntawm cov hluav taws thiab cov cua sov. Qhov kub ntawm kev khaws cia yuav tsum tsis pub tshaj 37°C. Khaws lub thawv kom nruj. Lawv yuav tsum khaws cia cais ntawm cov tshuaj oxidants, acids, hmoov hlau, thiab lwm yam, thiab tsis txhob khaws cia sib xyaw. Siv cov teeb pom kev zoo thiab cov chaw ua pa uas tsis tawg. Txwv tsis pub siv cov khoom siv kho tshuab thiab cov cuab yeej uas yooj yim rau hluav taws xob. Thaj chaw khaws cia yuav tsum muaj cov khoom siv tso tawm thaum muaj xwm txheej ceev thiab cov khoom siv tiv thaiv tsim nyog.
2. Ntim rau hauv cov thoob yas, nrog qhov hnyav tag nrho ntawm 180kg ib thoob. Khaws cia rau qhov chaw txias thiab muaj cua nkag, thiab khaws cia thiab thauj mus los raws li cov cai ntawm cov tshuaj uas yooj yim hlawv thiab muaj tshuaj lom.
