Malo opangira magetsi pogwiritsa ntchito madzi m'malingaliro mwanga ndi okongola kwambiri, chifukwa kukongola kwawo kumapangitsa kuti zikhale zovuta kuti anthu asawaone. Komabe, m'nkhalango zopanda malire za Greater Khingan ndi nkhalango zobiriwira, n'zovuta kuganiza momwe malo opangira magetsi pogwiritsa ntchito madzi okhala ndi chinsinsi angabisikire m'nkhalango zakuthengo. Mwina chifukwa cha malo ake apadera komanso obisika, "malo opangira magetsi ochokera kumpoto kwambiri ku China" awa akhala akudziwika kwa nthawi yayitali ngati nthano.
Pa msewu wa makilomita 100 kuchokera ku Huma County kum'mwera, palibe chomwe chimafala kwambiri kuposa malo okongola a nkhalango yamapiri m'dera la nkhalango ya Greater Khingan. Kusintha kwa nyengo kumakhala kokongola nthawi ya autumn, koma palibe malo opezera magetsi opangidwa ndi madzi pamsewu. Titafika ku Kuanhe Village, motsogozedwa ndi malangizo, tinapeza "chizindikiro" cha malo osadziwika opangira magetsi opangidwa ndi madzi.
Ngakhale kuti ndi malo ofunikira kwambiri, malo opangira magetsi amagetsi kumpoto kwambiri ku China, ngakhale kuti anali obisika m'minda yachonde ya Xing'an chifukwa cha malo ake pa Taoyuan Peak, kale anali otchuka chifukwa cha kutali ndi bata lake.
Ngati chilichonse chikufunika nthawi yabwino komanso malo abwino, ndiye kuti malo ochitira magetsi a Taoyuanfeng Hydropower Station agwiritsa ntchito kale mwayi wa malowo. Mothandizidwa ndi mapiri ataliatali a Phiri la Wuhua komanso madzi ambiri komanso othamanga a mtsinje wotchuka wa Heilongjiang, Mtsinje wa Kuanhe, uli pamtunda wosakwana makilomita 10 kuchokera ku mtsinje wa Heilongjiang womwe uli pakati pa China ndi Russia, ndipo uli pafupi ndi gawo lopapatiza kwambiri la gombe lalikulu kwambiri padziko lonse lapansi, "Dulikou", lomwe lili pamtunda wa makilomita 20. Malo ochitira magetsi amadzi omwe sakudziwika bwino ali m'mapiri koma amagwiritsa ntchito zabwino zonse zachilengedwe za dera lozungulira.
Monga "moyo" wa malo opangira magetsi pogwiritsa ntchito madzi, Mtsinje wa Kuanhe umapereka mphamvu yofunika kwambiri popanga magetsi pobwereka madzi. Monga mtsinje waukulu wa Heilongjiang, Mtsinje wa Kuan umachokera kudera lamapiri lalitali mamita 624.8 m'mapiri a m'malire a mtsinje wa Huma County. Madziwo amayenda kudzera kumpoto kwa Huma County ndi Sanka Township, ndipo amalowa mu Heilongjiang pamtunda wa kilomita imodzi kumpoto kwa Sanka Township. Mtsinje wa Kuanhe ulinso ndi mathithi ambiri, kuyambira mamita 5 mpaka mamita 26 m'lifupi, chifukwa cha kuyenda mofulumira kwa madzi - kuchuluka kwa madzi okwana ma cubic metres 13.1 pa sekondi - zomwe zimapangitsa kuti pakhale malo opangira magetsi pogwiritsa ntchito madzi.
Malo owonera zinthu apadera amangidwa pamwamba pa Phiri la Wuhua, komwe kuli malo opangira magetsi amadzi, moyang'ana malo ambiri a dziwe lonselo.
Mu 1991, malo oyamba a siteshoni yamagetsi ya Taoyuanfeng iyi yodabwitsa pang'ono anali ndi dzina lamakono kwambiri - Tuanjie Hydropower Station ku Huma County. Poyamba kumanga malo opangira magetsi amadzi, lingaliro linali loti liziyang'ana kwambiri pakupanga magetsi, komanso poganizira kugwiritsa ntchito bwino njira zowongolera kusefukira kwa madzi, ulimi wa nsomba, ndi mapulojekiti ena akuluakulu osamalira madzi ndi malo opangira magetsi amadzi.
Malo oyendetsera beseni la dziwe ndi 1062 sikweya kilomita, ndipo malo osungiramo zinthu ndi okwana ma cubic metres 145 miliyoni. Chigawo chachikulu cha damu chili ndi kutalika kwa mamita 229.20, chigawo cha khoma la mafunde chili ndi kutalika kwa mamita 230.40, chigawo chachikulu cha damu chili ndi kutalika kwa mamita 266, chigawo chothandizira cha damu chili ndi kutalika kwa mamita 370, ndipo mphamvu yokhazikika ya siteshoni yamagetsi ndi 3 X 3500 kilowatts. Muyezo wa kapangidwe ka uinjiniya wa kusefukira kwa madzi ndi kamodzi pazaka 200 zilizonse.
Komabe, kuyambira pomwe ntchito yomanga inayamba pa Disembala 18, 1992, chifukwa cha mavuto azachuma, panali zinthu zingapo zabwino ndi zoipa pa ntchito yomanga. Pomaliza, pa Julayi 18, 2002, patatha zaka khumi, ntchito yoyesera ndi kupanga magetsi inayenda bwino, zomwe zinadzaza kusiyana kwa kusowa kwa mphamvu zamagetsi zamadzi kumpoto kwa China. Mpaka pano, malo opangira magetsi amadzi a kumpoto kwenikweni omwe ali mu Greater Khingan yobiriwira "akulamulira" kumpoto kwenikweni kwa China.
Popeza msewu wa simenti unali kumangidwa, mapazi ake anafika mosavuta pakati pa phiri. Nsanja yayitali ya damu, yobisika ndi mapiri ataliatali, potsiriza inatsegula chophimba cha nkhalango yowirira ndikuyima patsogolo pawo. Atayang'ana mozungulira, mwadzidzidzi anaima pamwamba pa damu ndikutembenuka. Nyumba ya fakitale inali yobisika pakati pa mitengo pansi, yomwe inkaoneka ngati ili pansi koma inali yofanana ndi njira yotayira madzi ya damu. Kuchokera ku nyumba zotsala zothandizira, munthu akhoza kulingalira kukula kwakukulu kwa malowa.
Poyandikira damu, ngakhale kuti silili bwino ngati "chigwa chachitali chotuluka ku Pinghu" cha Zigwa Zitatu, zimakhala zovuta kubisa malo ake okongola a "mapiri ataliatali otuluka ku Pinghu". Phiri lozungulira la Wuhua lakhala litakutidwa ndi nkhalango pansi pa mphepo ya autumn yomwe imawomba Buddha, zomwe zimapangitsa kuti mapiriwo akhale amitundu yosiyanasiyana. Mitundu yosiyanasiyana iyi imaonekera ndipo imagawidwanso ndi madzi ambiri a damu, zomwe zimathandiza kuti malo okongola a autumn awa awonekere pamwamba pa madzi, ndikupanga mawonekedwe okongola a malo, ndikutulutsa chithunzi chabwino kwambiri cha pamwamba pa madzi.
Omanga akale anajambula mapiri ndi misewu, ndikupanga nyanja yabwino kwambiri yamapiri pamodzi ndi Phiri la Maluwa Asanu ndi damu. Ngakhale kuti linali lopangidwa, linali ngati cholengedwa chachilengedwe. Pafupi ndi phiri pafupi ndi damu, zizindikiro zakumbidwa zikuonekabe, ndipo nyanja yomwe ili patsogolo pake ilinso ndi gombe lalikulu la madzi amtendere lomwe "lili" pano mwakachetechete chifukwa cha kuchuluka kwa madzi amtsinje omwe amaperekedwa ndi chilengedwe.
Sikuti ndi yosalala komanso yopanda chopinga, komanso pansi pa madzi oyera awa, palinso nsomba zambiri zosungiramo madzi zomwe zimasambira momasuka. Monga "mnzawo wabwino kwambiri" wosungira madzi, nsomba zosungiramo madzi m'madzi sizimangoyeretsa madzi okha, komanso zimapatsa anthu am'deralo nyama yatsopano yokoma kwambiri ya nsomba. Pamwamba pa sitepe yopapatiza yamwala pafupi ndi damu, sikelo yoyezera kutalika kwa madzi inayikidwa kuyambira pamwamba mpaka pansi, yomwe kale inali "njira yogwirira ntchito yapadera" yodziwira kuchuluka kwa madzi. Panthawiyi, inakhala njira yachidule yoti anthu am'deralo atsikire pamwamba pa ayezi m'madzi ozizira. Mwa kukumba mabowo a ayezi pamwamba pa ayezi, nsomba zokhala ndi mitu yotuluka zimatha kuluma mbedza, zomwe zimapangitsa kuti ikhale "kuluma kokoma" kosazolowereka m'nyengo yozizira.
Ndikuyenda mozungulira gombe la damu, damu limapanga mawonekedwe okongola a nyanjayi ndi mawonekedwe ake. Dzuwa lofunda la nthawi yophukira silikuwalanso ngati chilimwe, likuwonetsa chikasu cha lalanje chofunda pa nyanjayi. Pansi pa mphepo yofewa, mafunde ofewa a lalanje amapanga mafunde osaya. Pamene ndikusangalala ndi madzi omwe akutsika pang'ono, mwangozi ndinapeza malo apadera owonera pa Phiri la Wuhua, lomwe likuyerekezeredwa kuti ndi malo omwe ali pamwamba pa phirilo omwe ali ndi mawonekedwe abwino kwambiri.
Pakati pa phiri, njira ina inatsegulidwa kuti apitirize kuyang'anira mapiri. Chifukwa cha nkhalango zobiriwira zachilimwe, bwalo lofiira, lomwe kale linali lodziwika bwino, tsopano linali litaphimbidwa ndi nkhalango yowirira ndipo linali lovuta kupeza. Motsogozedwa ndi anthu am'deralo, "chizindikiro chachinsinsi" chinapezeka - m'nkhalango yamapiri komwe tinkafunafuna njira yathu, panali munda waukulu wa chimanga wokhuthala kumanzere kwa msewu wadothi wotsetsereka. Tsatirani minda ya chimanga ndikupeza njira yosavuta yopangidwa ndi njerwa zofiira zobisika kwambiri, zopita ku bwalo lofiira lodabwitsa ili pamwamba pa phiri.
Lowani mwachangu m'chipinda chochezera, ndipo nthawi yomweyo, utsi wokongola ndi kukula kwa dziwe zimaonekera, zozunguliridwa ndi minda yachonde yambiri komanso nkhalango zowirira. Mukakwera makwerero amatabwa kupita ku chipinda chachiwiri cha chipindacho, mawonekedwe ake amakhala okulirapo. Kuwala kwa dzuwa kwa nthawi yophukira kumaonekera pamwamba pa madzi, kukuwonetsa mitundu yosiyanasiyana ya buluu. Ndi bata ndipo sizodabwitsa, ndipo kumatsagana ndi mapiri ndi nkhalango mbali zonse ziwiri. Kukula ndi kukula kwa pamwamba pa nyanjayi n'kovuta kuigwira mokwanira nthawi yomweyo.
Mwadzidzidzi, kuwala kwasiliva kunaonekera m'madzi dzuwa likulowa, ndipo anthu am'deralo anati nsombazo zinkasonkhana pamodzi padzuwa lofunda, zikudumphadumpha m'madzi mwachangu. Kuwala kwasiliva kunawala kwambiri ndi kuthwanima kwa mamba a nsomba, ndipo pa chetecho, phokoso lochepa la mphepo ya m'dzinja yomwe inkawomba m'mitengo mbali zonse ziwiri linamveka.
