Kwimibhalo evela kwiXesha laseNtwasahlobo nasekwindla kunye neXesha laMazwe alwayo, iipropathi ezinomtsalane zentsimbiimagnethizarekhodwa ngokuphindaphindiweyo.Umzekelo, "ilitye umazibuthe libiza intsimbi" kwi "Lu Shi Chun Qiu" ebhalwe ngenkulungwane yesithathu BC, kwaye "ilitye umazibuthe ubiza inaliti" kwi "Guiguzi" hayi kude omnye komnye zombini.Ngeli xesha, umazibuthe mhlawumbi wawuqondwa kakhulu kwaye uthelekiswa nomtsalane kamama onothando ebantwaneni bakhe.
UGao Yao we-Eastern Han Dynasty kwinkcazo yakhe ethi "Lu Shi Chun Qiu": Ilitye ngumama wentsimbi, kodwa kukho amatye anobubele nangenabubele.Ilitye elinobubele linokutsala abantwana balo (intsimbi), kodwa ilitye elingenabubele alinakutsala..Ngoko ke, phambi kobukhosi bakwaHan, iimagnethi zazibhalwe ngokuthi "Ci Shi", oku kuthetha "Ilitye loBubele".
Emva kwexesha, abantu basebenzise iimagnethi ukuzama ukutsala ezinye iintsimbi okanye izinto.Waba yintoni umphumo?
Incwadi ethi "Huainanzi" ebhalwe kwi-Western Han Dynasty yabhala: "Ukuba ilitye elinobubele linokudibanisa isinyithi, kuya kuba nzima ukulisebenzisa ukukhokela iileyile.""Ayikwazi ukudibanisa nobhedu."Ngexesha loBukumkani obuThathu, omnye umntu wathi: "Ilitye lobubele alinakugotywa."Izinto ezibizwa ngokuba "zinaliti ezigobileyo" mhlawumbi zibhekisa kwiinaliti ezenziwe ngeentsimbi ezinjengegolide, isilivere kunye nobhedu, ngokuqinisekileyo azitsalwanga ziimagnethi.
Ezi rekhodi zibonisa ukuba i-Han Dynasty yaqaphela ukuba imagnethi inokutsala intsimbi kuphela kodwa kungekhona ezinye izinto.Le yinkqubela kancinane.Siyazi ukuba imagnethi inokutsalelana kuphela kwintsimbi, kodwa ukuba iimagnethi zisondelelene, imeko inzima kakhulu.Iimagnethi zihlala zineepali ezimbini, enye ibizwa ngokuba yipali yasezantsi kwaye enye ibizwa ngokuba yipali yasentla.Ngelo xesha, kwakukho an Ingcali yealchemist egama linguLuan Da owenza oomazibuthe ababini, ababefana neziqwenga zechess kwaye besondelelene.Kwathiwa abakwazanga kuphela ukutsala omnye komnye ("ukukhansela omnye komnye"), kodwa "bagxotha ngokungapheliyo", oko kukuthi, ukugxotha omnye nomnye.Le yinto ebizwa ngokuba yi-"fighting chess" iqhinga.Wenza eli qhinga kuMlawuli uWu weHan Dynasty,kwayeumlawuli wayehlekisa, ngoko ke wafumana isikhundla esisemthethweni se "Five-profit General".
