Ukuqala kwekwindla lixesha leshumi elinesithathu lelanga "yeMigaqo yeSolar yamashumi amabini anesine" kunye nekota yokuqala yelanga ekwindla. UDou ubhekisa kumzantsi-ntshona, ilanga lifikelela kwi-135° ecliptic longitude, kwaye lidibana ngoAgasti 7 okanye 8 wekhalenda kaGregory minyaka le. Ukutshintsha kwendalo yonke yinkqubo kancinane. Ukuqala kwekwindla yindawo yokuguquka xa i-yang qi iyancipha ngokuthe ngcembe, i-yin qi ikhula ngokuthe ngcembe, kwaye i-yang qi iguquka ngokuthe ngcembe ibe yi-yin qi. Kwindalo, yonke into iqala ukukhula ukusuka ekuchumeni ukuya emfiliba nasekuqoleni.

Ukuqala kwekwindla akuthethi ukuphela kwemozulu eshushu. Ukuqala kwekwindla kusekwixesha elitshisayo, kwaye ihlobo alikaphumi. Ixesha lesibini lelanga ekwindla (ekupheleni kwehlobo) kusehlotyeni, kwaye imozulu iseshushu kakhulu ekuqaleni kokwindla. Okubizwa ngokuba "ubushushu bukwi-volts ezintathu", kwaye kukho intetho ethi "i-volt enye emva kwekwindla", kwaye kuya kubakho ubuncinane "i-volt enye" ​​yemozulu eshushu kakhulu emva kokuqala kwekwindla. Ngokwendlela yokubala ye "San Fu", usuku lwe "Liqiu" luhlala luphakathi kwexesha, oko kukuthi, ihlobo elishushu alikapheli, kwaye ukupholisa kokwenyani ngokuqhelekileyo kuza emva kwexesha le-solar yaseBailu. Indawo yamanzi ashushu kunye nepholileyo ayiqalisi ekwindla.

Emva kokungena ekwindla, iyatshintsha ukusuka kwimvula, efumileyo kwaye ishushu ehlotyeni ukuya kwindawo eyomileyo neyomileyo ekwindla. Kwindalo, i-yin kunye ne-yang qi iqala ukutshintsha, kwaye zonke izinto ziyancipha ngokuthe ngcembe njengoko i-yang qi iyancipha. Olona tshintsho lucacileyo ekwindla kuxa amagqabi ehla ukusuka eluhlaza ukuya kumthubi aze aqalise ukuwisa amagqabi kwaye izityalo ziqala ukukhula. Ukuqala kokwindla lelinye “lamaxesha amane onyaka nemithendeleko esibhozo” kumaxesha amandulo. Kukho isiko phakathi kwabantu lokunqula oothixo belizwe nokubhiyozela isivuno. Kukwakho amasiko afana “nokuncamathela ngamafutha asekwindla” kunye “nekwindla elumayo”.
