Faiga faʻavae o le toe faafoi

O mea e toe faafoi e talia i totonu o le 40 aso pe a o le aso e maua ai oloa. E le mafai ona toe faafoi pe fesuiai mea faʻapitoa. O mea na faʻatauina ma se kata meaalofa e mafai ona fesuiai; e le talia toe totogi.

Meaalofa e leai se totogi

Susū mai i Roymall, lau upega tafaʻilagi faʻapolofesa mo le faʻatauina o meaalofa maualuga. Matou te faʻatauaina ma talisapaia lau lagolago, ma matou te fia faʻaalia la matou faʻafetai e ala i le faʻaopoopoina o se lagona fiafia i au faʻatauga. A e faʻatau mai ia i matou, e le gata e te maua oloa maualuga e faʻaleleia ai lou olaga, ae o le a e mauaina foi se meaalofa e leai se totogi i soʻo se oka e te faia. Sauni e suʻesuʻe la matou aoina ma maua au meaalofa lelei? Suʻesuʻe la matou filifiliga o oloa maualuga, fai lau oka, ma faʻatali mo le fiafia o lau meaalofa e leai se totogi e oʻo mai faʻatasi ma lau faʻatauga.

Faiga faʻavae o uta

O le a matou galulue malosi e momoli atu oloa ia te oe pe a uma ona maua au oka ma faʻamautinoa e saogalemu le taunuu. O faʻamatalaga o le uta o le a tuʻuina atu i lau imeli faʻamaonia.I le tele o tulaga, o oka e faʻatautaia i totonu o le 2 aso. I tulaga faʻapitoa, o le a tuai e pei ona taua i lalo: A e faia se oka i le Aso Toʻonaʻi, Aso Sa poʻo aso malolo, o le a tuai mo le 2 aso.E masani lava, e manaʻomia le 5-7 aso faigaluega (Aso Gafua i le Aso Faraile) e aunoa ma le aʻafia i le tuai o vaalele poʻo isi mea tau siosiomaga.Talu ai o la matou auaunaga uta o le lalolagi atoa, o taimi o le uta o le a faʻalagolago i lou nofoaga, ma atonu e manaʻomia ai sina taimi ma faʻatali ma le onosaʻi pe afai o loʻo e i totonu o itumalo mamao poʻo atunuʻu.
