Daim Ntawv Thov Loj: Nws yog rau 1 txog 50 tons nyob rau hauv feem ntau cov xwm txheej, tab sis peb tuaj yeem ua kom nws loj dua kom haum rau cov neeg siv khoom xav tau.

Yam ntxwv:

a.Ob hom hniav (ib zaug lossis ob) hom thiab cov hniav tuaj yeem ua rau cov kev xav tau sib txawv.
b.Qhov tshwj xeeb zoo li, uas nws qhov dav dav dav ntev dua li qhov dav dav, tso cai rau lub trench lossis channel ua qhov loj me thiab ncaj ncaj.

Nta:

Txo qhov hnyav nrog cov khoom zoo, puas-resistant.
