M'zolemba za Nyengo ya Spring ndi Autumn ndi Nyengo Yankhondo za States, zinthu zokopa zachitsulo zamaginitozinalembedwa mobwerezabwereza.Mwachitsanzo, "mwala maginito kuitana chitsulo" mu "Lu Shi Chun Qiu" olembedwa m'zaka za zana lachitatu BC, ndi "maginito mwala kuitana singano" mu "Guiguzi" osati kutali wina ndi mnzake.Panthawiyi, magnetism mwina inali yodziwika bwino ndikufanizidwa ndi kukopa kwa mayi wachikondi kwa ana ake.
Gao Yao wa ku Eastern Han Dynasty m’mawu ake a “Lu Shi Chun Qiu” anati: Mwala ndi mayi wachitsulo, koma pali miyala yachifundo ndi yosakoma mtima.Mwala wokoma mtima ukhoza kukopa ana ake (chitsulo), koma mwala wosakoma mtima sungathe kuukoka..Chifukwa chake, Mzera wa Han usanachitike, maginito adalembedwa kuti "Ci Shi", kutanthauza "Mwala Wachifundo".
Kenako, anthu ankagwiritsa ntchito maginito pofuna kukopa zitsulo kapena zinthu zina.Kodi zotsatira zake zinali zotani?
Buku lakuti "Huainanzi" lolembedwa ku Western Han Dynasty linalemba kuti: "Ngati mwala wokoma mtima ungalumikiza chitsulo, zimakhala zovuta kuugwiritsa ntchito kutsogolera matailosi.""Sizingagwirizane ndi mkuwa."Pa nthawi ya maufumu atatu, munthu wina ananenanso kuti: "Mwala wachifundo sungathe kupindika."Zomwe zimatchedwa "singano zokhotakhota" mwina zikutanthauza singano zopangidwa ndi zitsulo monga golide, siliva, ndi mkuwa, zomwe ndithudi sizimakopeka ndi maginito.
Zolemba izi zikuwonetsa kuti Mzera wa Han unazindikira kuti maginito amatha kukopa chitsulo koma osati zinthu zina.Izi ndikupita patsogolo pang'ono.Tikudziwa kuti maginito amatha kukopana kuchitsulo, koma ngati maginito ali pafupi wina ndi mzake, zinthu zimakhala zovuta kwambiri.Maginito nthawi zonse amakhala ndi mitengo iwiri, imodzi imatchedwa south pole ndipo ina imatchedwa kumpoto.Pa nthawi imeneyo, panali an katswiri wa alchemist wotchedwa Luan Da yemwe anapanga maginito awiri, omwe ankawoneka ngati zidutswa za chess ndipo zinali zoyandikana wina ndi mzake.Zinanenedwa kuti iwo sakanakhoza kukopana ( "kuletsa wina ndi mzake"), komanso "kuthamangitsana kosatha", ndiko kuti, kuthamangitsana.Izi ndi zomwe zimatchedwa "kumenyana chess".Adachita chinyengo ichi kwa Emperor Wu wa Mzera wa Han,ndimfumuyo inasekedwa, kotero iye adalandira udindo wa "Five-profit General".
