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.
