Ko te Kōhatu Yuhua he toka tūturu i hangaia e te kaha o te rere o te wai i roto i ngā manga awa me ngā awa matua, me te whakapūtanga o ngā kohuke i roto i ngā mano ki ngā miriona tau—he tohu ahurei o ngā huringa whenua me te wai ia kohatu. I ahu mai i ngā pūnaha awa me ngā manga maha e piko ana i roto i ngā puke maunga me ngā rohe mania whānui: ko ngā wai e neke puhoi ana i roto i ngā manga whaiti, piko ka whakaiti i te waku, ka taea ai e ngā matūriki kohuke pai (e haria ana e te wai ua i a ia e uru ana i roto i ngā toka karāhe me te toka kōhatu e karapoti ana) te tau mārire ki runga i ngā kongakonga toka taratara. Ko ēnei kongakonga, i te tīmatanga he koki me te koretake, ka rere mārire ki roto i ngā awa matua e tere ana te rere, ka panaia e ngā ia pōrearea ki te kirikiri, te onepu koi me ngā toka papatahi o te awa—ka whakakanapahia e tēnei tukinga tonu ō rātou mata papatahi, papatahi, ka haehae i ngā taha, ka whakangawari i ngā āhua. Ko ngā kohuke pēnei i te quartz (e tāpiri ana i te māramatanga mārama e hopu ana, e marara mārie ana i te mārama, e kitea ai ngā uaua i raro i te kanapa tūturu), te feldspar (e kawe mai ana i ngā tae rei ngawari, māwhero mārama rānei e neke haere ana me te nui o te rā e whiwhi ana i te wā hanganga) me ngā waikura rino (e hanga ana i ngā tae whero waikura, i te amipere honi rānei e hohonu ake ana i te noho roa o ngā kongakonga i roto i ngā wai pāpaku whai hāora) ka rewa ki roto i te wai awa paku waikawa (e hangaia ana e ngā mea tipu pirau) ka uru ki roto i ngā kapiti iti me ngā pūwero o ngā kongakonga. I te mea ka piki ake ngā taumata wai o te ua o te wā, ka huri haere tonu ngā kongakonga i waenga i ngā manga me ngā awa matua: i roto i ngā manga, ka tukuna e ngā ia puhoi ngā kohuke kia hanga i roto i ngā paparanga matotoru, ōrite; i roto i ngā awa matua, ka tapahia e ngā rerenga tere ngā awa angiangi, ngā awa piko i roto i ngā putunga kohuke. Ka hangaia e tēnei huringa he uaua ahurei—he whānui ake, he ōrite ake ngā uaua o ngā kōhatu manga pērā i ngā tukutuku pungawerewere e horapa ana, ko ngā kōhatu awa matua he uaua angiangi ake, he piko ake pērā i ngā miro whiri, ka waiho ia Kōhatu Yuhua hei "rātaka" tūturu o tōna nekehanga tonu i waenga i ngā wāhanga awa rerekē.

Ko ngā āhuatanga matua o te Kōhatu Yuhua ko ngā tauira uaua rerekē, te kakano maeneene, me ngā āhua rauropi pakari e mau ana i ngā tohu wai mārama - ngā āhuatanga e wehe ke ai i ngā kōhatu whakapaipai horihori. He rerekētanga whai rawa, kāore e taea te whakahoki mai i ngā uaua: ko ētahi he rite ki ngā uaua rau ngawari e horapa ana ki waho mai i te "kakau" o waenganui ki ngā taha kōhatu, ko ētahi he rite ki ngā aho kapua angiangi e miro mārie ana i te mata me te mea he tio i te nekehanga, ko ētahi he rite ki ngā pata tomairangi marara, ki ngā puku putiputi iti rānei e huihui ana i te kokonga kotahi, ā, ko ētahi ka hanga i ngā āhua ngoikore, āhua-āhua e whakaoho ana i ngā maunga tawhiti, i ngā awa e rere ana rānei. Ka whakaranua ngā tae mai i te mārama ki te pōuri i roto i ngā whakatakotoranga korekore me te kore he rohe koi - ka memeha te feldspar māwhero mārama ki te rei, kātahi ka huri ki te waikura rino amber honi, ka hanga i ngā oro ōrite. Ko ngā tekau tau o te whakakanapa awa tonu ka muku i ngā taha taratara me ngā kokonga koi katoa, ka waiho te mata o te Kōhatu Yuhua kia maeneene kia rere ngā maihao ki runga me te mea he reti i runga i te hiraka kua whakakanapahia; he mātao, he whakahauora ina pā ki te raumati wera, ehara i te makariri hukapapa pērā i te konganuku, me te pupuri tonu i te mahana ngawari, whakamarie i te hotoke makariri nā tōna hanganga kohuke matotoru e pupuri ana i te wera roa atu i te rakau. Ina pāngia e te māramatanga taiao, ka puta he kanapa ngohengohe, kāore e kanapa: ka whiti te rā o te ata mā roto i ngā matapihi hei whakaputa i te hohonutanga o ngā uaua, ka puta he kanapa mahana mai i te māramatanga o te rama o te ahiahi, ā, ahakoa i ngā rā kapua, ka mau tonu te kanapa mārie. He rerekē ngā āhua i runga i te kaha o te rere o te wai: ko ngā kōhatu porowhita iti, kiato (he rite te rahi ki ngā māpere, ki ngā ringa iti rānei) i ahu mai i ngā wāhanga awaawa matua pōrearea, i reira ka karapotia rawatia e te kaha tukinga kaha, ko ngā kōhatu nui ake, papatahi, paku piko rānei (tae atu ki te rahi o te nikau, o ngā pereti iti rānei) ka hangaia i roto i ngā awa marino, i reira ka āta hangaia e te pēhanga wai ngawari. He pakari taiao ngā Kōhatu Yuhua katoa—ka ātete ki te mau o ia rā mai i te whakahaere, ka manawanui ki ngā pāmahana teitei (tae atu ki ngā rau nekehanga tata ki ngā ahi ahi me te kore e pakaru) ā, ka tū atu ki ngā huarere o waho pērā i te ua, te hukarere me te hihi UV e memeha ana i ngā rauemi horihori.

He nui te whakanui a te rāngai whakapaipai ahi o waho i te Kōhatu Yuhua mō tōna ātete wera pai, tōna ataahua taiao me tōna whaihua, ā, he mea nui tēnei hei whakapaipai mō ngā wāhi ahi taupee e whakataurite ana i te haumaru me te ataahua. He whānuitia te whakamahinga i roto i ngā momo whakatakotoranga ahi, mai i ngā rua ahi iti o muri ki ngā wāhi huihuinga taupee nui. Ko ngā Kōhatu Yuhua papatahi, matotoru (tata ki te rua ki te toru henimita te matotoru, i whiriwhiria mō tō rātou hanganga kohuke matotoru e pai ake ana te ātete ki te wera) ka whakatakotoria marietia ki roto i tētahi porowhita pai huri noa i ngā rua ahi hei rohe whakamahana wera—ehara i te mea ka aukati noa tēnei ārai i ngā mura e rere ana mai i te mura i te tarutaru maroke e karapoti ana, i ngā papa rakau, i ngā whāriki o waho rānei (he painga haumaru nui atu i te kirikiri wetewete), engari ka hangaia hoki e ō rātou uaua tae he rerekētanga whakamiharo ki te whakarewa ahi pouri me ngā tipu taupee matomato, ka tāpirihia he paparanga tirohanga kāore i roto i ngā rohe raima mangu. Ko ngā kōhatu rahi-waenga me ngā turanga papatahi, pumau (tata ki te rahi o ngā pereti tina, i whiriwhiria mō tō rātou tohatoha taumaha ōrite) ka whakatakotoria ki te taha o ngā nohoanga ahi—ahakoa he paepae rakau, he sofa o waho, he tūru Adirondack rānei—hei tēpu taha whaihua. He ngāwari ki te pupuri i ngā inu (pēnei i ngā kapu pia hukapapa, ngā kapu koko wera, ngā karāhe tī hukapapa rānei), ngā kai mātao (pēnei i ngā peihana nati, ngā putea māshmallow hei tunu, ngā pereti pihikete rānei) ngā taputapu whakakā ahi rānei (pēnei i ngā mati ārai wai, ngā pōka ahi iti, ngā whakakā ahi kī tonu i te miro).

He ngāwari te horoi i tōna mata maeneene i muri i te whakamahinga—tae atu ki te pungarehu, ngā toenga marshmallow piri, ngā paru inu rānei i maringi, ka taea te tango atu ki te kakahu haukū i roto i ngā hēkona, kāore he kaihoroi kino e hiahiatia ana. Ka whakanui ake ētahi kaipupuri whare i te whakapaipai mā te whakarārangi i ngā kōhatu o ngā rahi rerekē (mai i te iti ki te rahi o te ringa ki te nui ki te rahi o te nikau) hei hanga arai whakapaipai iti, koretake huri noa i ngā wāhi ahi—ka wehea e ēnei arai te rohe ahi mai i ngā wāhi kai taupee, ngā wāhi whakato rānei, ka tautuhi mārie i te wāhi, ā, ka whakarato i ngā wāhi nohoanga tāpiri mō ngā manuhiri i ngā huihuinga nui. Mā te ātete wera o Yuhua Stone ka kore e pakaru, e pakaru, e memeha rānei ahakoa te maha o ngā wā ka pāngia e te wera ahi me ngā huringa whakamatao. Ka ātete hoki tōna hanganga kohuke matotoru ki te horo o te ua—i muri i te ua nui, ka tere te maroke o ngā kōhatu, ā, ka mau tonu ō rātou tae taketake, i te mea ka tupu mārire te moko i roto i ngā kapiti i waenganui i a rātou i roto i te wā, ka uru hohonu atu ki te taiao o waho. Ahakoa e whakamahia ana mō te haumaru, te mahi, te whakapaipai rānei, ka hurihia e Yuhua Stone ngā wāhi ahi noa hei wāhi mahana, ataahua e hono ana ki te taiao.
