1. No ke aha ʻoe e koho ai iā mākou?

Aia kā mākou hui ma Alibaba.com no 12 mau makahiki.Mālama mākou i ka maikaʻi o nā huahana, aia nā kānaka kūikawā no ka maikaʻi.

Inā loaʻa iā ʻoe ke kumu kūʻai haʻahaʻa mai nā mea hoʻolako ʻē aʻe, e uku mākou i ʻelua manawa i nā mea kūʻai aku e pili ana i ke kumukūʻai kiʻekiʻe.

2. Pehea ka lōʻihi o kāu manawa hāʻawi?

E like me ka nui.Ma keʻano maʻamau i loko o 2-7 mau lā inā i ka waihona.A 15-20 mau lā ināʻaʻole i ka waihona.

3.He aha kāu mau hua'ōlelo uku?

A: E T / T 30% ma mua, a me 70% ma mua o ka lawe ʻana.

B: 100% L/C i ka ʻike.

C: Na T / T 30% ma mua, a me 70% L / C i ka ʻike.

4.Ke hāʻawi neiʻoe i nā laʻana?He manuahi anei?

ʻAe, hāʻawi mākou i ka hāpana no ka manuahi akā ʻaʻole e uku i ke kumukūʻai o ka ukana.

5.He aha inā ʻaʻole ʻoluʻolu ka mea kūʻai?

Inā he pilikia me ka huahana, lawe mākou i ke kuleana piha.

Inā he pilikia ma ke kaʻina hana, e kōkua mākou iā ʻoe e hoʻoponopono.
