Nrụgide mkpọpu na-atachi obi na-eme ihe na nkume site na ezé, na-eme ka nkume ahụ gbajie (mmetụta crushing). N'oge usoro ntụgharị, cone na-ejikọta ala nke olulu mmiri ahụ na otu ezé na ezé abụọ, na ọnọdụ nke etiti cone na-agbanwe, na-eme ka ọkpụkpụ ahụ na-ama jijiji ogologo oge. Mmaji ogologo ogologo a na-eme ka eriri egwu na-aga n'ihu na-akpakọ ma gbatịa. Ụdọ mgbọ ala nke dị ala na-agbanwe ike nrụrụ mgbanwe a na-agbanwe kwa oge ka ọ bụrụ ike na-eme ka e guzobe site na ezé iji mebie nkume.
