Pahū ʻo Shenhai
ʻO kahi hiʻohiʻona nui e noʻonoʻo ai no nā mea metala i loko o nā mea uila pahū-hōʻoia ko lākou makemake e hoʻāla i nā hui kinoea-ea pahū ma o nā ʻōhū mechanical.. Ua hōʻike ʻia ka noiʻi ʻana he kuleana koʻikoʻi ke ʻano o kēia mau metala i ko lākou hiki ke hoʻā. No ka pale ʻana i ka hiki ʻana mai o ka ʻā ʻana o ka mīkini i loko o nā pā metala, ua kauoha ʻia nā palena kikoʻī. Nā kūlana no pahū kaiapuni – Pono Lako Nui – e hoakaka i keia:
