1. O le faagasologa o le gaosiga autu o paipa u'amea su'esu'e vevela (fa'agasologa asiasiga autu):
Tupa avanoa avanoa ma asiasiga → faʻavevela faʻalava faʻalava → tui → taʻavale paipa → toe faʻamafanafana uʻamea → faʻamau (faʻaititia) le lautele → vevela △ → faʻamaʻi faʻamaʻa faʻamaʻa → faʻamaeʻaina → asiasiga (e le faʻaleagaina, faaletino ma vailaʻau, asiasiga Taiwan) → fale teu oloa
2. Le faiga autu o le gaosiga o le malulu-taai (toso) paipa uʻamea seamless:
Sauniuniga pili → u'u pickling → ta'avale malulu (tusi) → togafiti vevela → fa'asa'o → fa'amae'a → asiasiga
