Yuav tsum ua kom tiav raws sijhawm. Tsis tas li ntawd, xyuam xim rau qhov chaw ntawm cov khoom siv thiab seb puas muaj cov qauv kev tiv thaiv cuav kom ntseeg tau tias nws zoo.
2. Yog tias koj yuav tsum tau nruab cov kav dej kub thiab dej txias, koj yuav tsum tsim qhov kev ncua deb ntawm ob lub kav dej, tsis pub tsawg dua peb centimeters. Tsis tas li ntawd, nyob rau theem pib ntawm grooving, txoj hauj lwm ntawm cov kav dej kub thiab dej txias yuav tsum tau txhais kom meej. Cov dej kub feem ntau yog nyob rau sab laug thiab dej txias yog nyob rau sab xis. Yog tias qhov xwm txheej hloov pauv, nco ntsoov piav qhia ua ntej, kom tsis txhob cuam tshuam rau kev siv ib txwm muaj.
3. Yog tias nws yog cov yeeb nkab hlau clamp, qhov kev ncua deb ntawm ob lub ntsiab lus yuav tsum tau tswj ntawm ntau tshaj 80cm.
