Icyayi cy'umuyugubwe“Zijuan”(Camellia sinensis var.assamica“Zijuan”) ni ubwoko bushya bwicyayi kidasanzwe gikomoka muri Yunnan. Mu 1954, Zhou Pengju, Ikigo cy’ubushakashatsi ku cyayi cy’ishuri ry’ubumenyi bw’ubuhinzi rya Yunnan, yavumbuye ibiti by’icyayi bifite amababi y’umuhengeri n’amababi mu busitani bw’icyayi bwa Nannuoshan mu Ntara ya Menghai. Dukurikije ibimenyetso byatanzwe na Zhou Pengju, Wang Ping na Wang Ping bateye ibiti by'icyayi muri Nannuoshan. Igiti cyicyayi gifite ibiti byumutuku, amababi yumutuku, nuduti twumutuku twabonetse mumurima wicyayi witsinda ryatewe.

Yabanje kwitwa'Zijian 'nyuma ihinduka' Zijuan '. Mu 1985, yororerwa mu buryo bwa gihanga mu bwoko bwa clone, maze mu 2005 yemererwa kandi irindwa n’ibiro bishya byo kurinda ibimera by’ubuyobozi bw’amashyamba ya Leta. Umubare wiburyo butandukanye ni 20050031.Gukata gukwirakwizwa no guhindurwa bifite igipimo kinini cyo kubaho. Irakwiriye gukura ku butumburuke bwa metero 800-2000, hamwe nizuba ryinshi ryizuba, ubushyuhe nubushuhe, ubutaka burumbuka nagaciro ka pH hagati ya 4.5-5.5.

Kugeza ubu, 'Zijuan' ifite igipimo runaka cyo gutera muri Yunnan kandi yagejejwe mu turere tw’icyayi mu Bushinwa kugira ngo duhinge. Ku bijyanye n’ibicuruzwa, abantu bakomeje gushakisha ubwoko butandatu bwicyayi bakoresheje icyayi cyumutuku cuckoo nkibikoresho fatizo, kandi ibicuruzwa byinshi byarakozwe. Nyamara, tekinoroji yo gutunganya yateje imbere icyayi cya Zijuan Pu'er nicyo gikuze cyane kandi cyakiriwe neza kandi kiramenyekana nabaguzi, bikora urukurikirane rwihariye rwibicuruzwa bya Zijuan Pu'er.

Icyayi kibisi cya Zijuan (icyatsi kibisi n'icyatsi cyumishijwe n'izuba): imiterere irakomeye kandi irakomeye, ibara ni umukara wijimye, umukara n'umuhengeri, amavuta kandi urabagirana; nziza kandi nshya, impumuro nziza yigituba yatetse, impumuro nziza yubuvuzi bwubushinwa, bwera kandi bushya; isupu ishyushye ni Umutuku wijimye, usobanutse kandi urabagirana, ibara rizaba ryoroshye iyo ubushyuhe bugabanutse; ubwinjiriro burasharira gato kandi burakomeye, burahinduka vuba, bugarura ubuyanja kandi bworoshye, bworoshye kandi bworoshye, bukize kandi bwuzuye, kandi buryoshye burigihe; ibara ryoroshye ryo hepfo yikibabi ni indigo ubururu.

Icyayi cyirabura cya Zijuan: Imiterere iracyakomeye kandi ipfunditse, iraremereye, yijimye gato, yijimye, isupu itukura kandi irabagirana, impumuro nziza kandi ifite impumuro nziza yubuki, uburyohe bworoheje, kandi hepfo yikibabi harakomeye gato n'umutuku.

Icyayi cyera cya Zijuan: Ibiti byicyayi bifatanye neza, ibara ryera ryera rya feza, kandi pekoe iramenyekana. Ibara ryisupu ni umuhondo wumuhondo wera, impumuro nziza iragaragara, kandi uburyohe ni bushya kandi bworoshye.

Icyayi cya Zijuan Oolong: Imiterere irakomeye, ibara ni umukara n'amavuta, impumuro irakomeye, uburyohe ni bworoshye kandi buryoshye, isupu ni umuhondo wa zahabu, naho hepfo yikibabi ni icyatsi kibisi cyijimye kandi gifite impande zitukura.
