I ka makahiki 2018, ua hiki i ka 2.35 biliona cubic mika ka nui o ka ʻāina, a i ka makahiki 2019, ua hōʻea ʻo ia i 2.4 biliona cubic mika, me ka piʻi ʻana o ka makahiki ma kahi o 3.46%.Ua helu ʻia ka hoʻohana ʻana i ka koneki ma Kina i ka honua no nā makahiki he 30.

Ma ka makahiki 2019, ua hiki i ka huina alanui nui o Kina i 4.8465 miliona mau kilomita, a ua hiki i ke alaloa he 142600 mau kilomita, e hoʻokūkū ana i ka honua * *.Ma ka hopena o 2019, ua hōʻea ka mileage o ke kaʻaahi Kina ma mua o 139000 km, me 35000 km o ke kaʻaahi kiʻekiʻe.

Ma ka hopena o 2018, aia he 851500 alahaka ala, me ka lōʻihi o 55685900 mika.15117 ua hoʻohana ʻia nā alahao kaʻaahi, me ka lōʻihi o 16331km;ma ka hopena o 2019, hiki i ka 6600km ka huina holo kaʻa holo kaʻa kaʻa ma Kina.

Aia ma hope o kēia mau ʻikepili nui ka nui o ka ʻenekinia hoʻolālā.Eia nō naʻe, e loaʻa ana nā pilikia like ʻole i ka hoʻohana lōʻihi ʻana i nā mea paʻa, ʻoi aku ka nui o nā "cancers" ʻekolu o ka haki ʻana, leakage a me ka pōʻino, i lilo i mau pōʻino huna nui e pili ana i kona lōʻihi a me ke ola lawelawe.

No kēia mau mea nui ka nui o ka hoʻopaʻi ʻana (ka mālama ʻana i ka wai, ka lawe ʻana, ka hana ʻoihana a me ka hana kīwila, ke kūlanakauhale, ka pūʻali koa, ka ikehu, a me nā mea ʻē aʻe), kekahi a ʻoi aku paha nā koi, e like me ke kūpaʻa ʻana o ka ʻūhā, ka hoʻoponopono ʻana, ka wai a me ka impermeability, ka acid a me ka corrosion resistance, ka paʻakai, carbonation resistance, freeze-thaw resistance, reinforcement, etc..
