(1) Kev faib tawm los ntawm cov duab geometric ntawm iav fwj
① Round iav fwj.Qhov hla ntawm lub raj mis yog puag ncig.Nws yog hom lub raj mis uas feem ntau siv nrog lub zog siab.
② Square iav fwj.Qhov hla ntawm lub raj mis yog square.Hom lub raj mis no tsis muaj zog dua lub raj mis puag ncig thiab nyuaj rau kev tsim khoom, yog li nws siv tsawg dua.
③ Curved iav fwj.Txawm hais tias tus ntoo khaub lig yog puag ncig, nws yog nkhaus hauv qhov siab qhov siab.Muaj ob hom: concave thiab convex, xws li vase type thiab gourd type.Cov style yog tshiab thiab nrov heev nrog cov neeg siv.
