I-Xuzhou yamandulo, ibuyele kumnombo we-YU, ineminyaka engaphezu kwama-2600 yembali yokwakhiwa kwesixeko. Isixeko yinqaba yomkhosi kunye namawaka eminyaka empumelelo. Kunyaka we-TianQi kwi-Ming Dynasty, uMlambo oMthubi waphinda wahanjiswa ngendlela, izikhukula zazihlala zisenzeka, kwaye isixeko sakudala sasintywila ngokuphindaphindiweyo. Isixeko esitsha saphinda sakhiwa kwindawo engentla kwesixeko esidala, esathi senza iintsalela zeXuzhou yamandulo “njengesiXeko esiphantsi kweSixeko, iSakhiwo esiphantsi kweSakhiwo, isitalato esiphantsi kwesitalato, kunye neNgcamle.”

IMyuziyam yoDonga lweSixeko iyilwe ngokwemeko yemo. Isebenzisa imeko elahlekileyo njengesikhokelo kunye nemowudi yolwakhiwo lwesithuba njengengqiqo ukuphonononga ukuchazwa komxholo kwindawo yoyilo.

Abayili balungelelanise iglasi yeprofayili ka-U ngokuthe nkqo ukwenza imvakalelo yesingqi ephindaphinda izakhiwo zomthi zemveli. Uphawu lwayo "lokudlulisa ukukhanya ngaphandle kokubona-ngaphaya" kwenza ukuba isakhiwo sibandakanyeke kwingxoxo efihlakeleyo kunye nebhloko yembali, ukugcina ubumfihlo ngelixa ukwazisa ukukhanya kwendalo. Umnqamlezo ogobileyo weIglasi yeprofayileiphosa ukukhanya okuqukuqelayo kunye neepateni zethunzi ezindongeni, ezitshintsha ngokuhamba kwexesha njengokuphefumla kwembali, inika isakhiwo esimileyo ngobuhle obuguqukayo.

Olona lutsha lunesibindi lulele ekusetyenzisweni kweIglasi yeprofayilekuphahla olusicaba, umzamo onqabileyo ngelo xesha. Icwangciswe ngendlela ethile, iglasi yeprofayile ye-U ilinganisa isingqi sophahla lwethayile lwemveli, ivuselela iinkumbulo zembali ngelixa inikezela ngobuhle bale mihla. Impembelelo "yemvula elula": ukukhanya kwelanga kudlula kwi-cross-shaped cross-section yeglasi, iphosa ukukhanya okufana nemvula kunye nezithunzi ngaphakathi, ukudala indawo ekhethekileyo yokukhanya kwendalo kwiiholo zemiboniso ephantsi komhlaba kunye nokusombulula ingxaki yokukhanya okungahambi kakuhle kwiindawo eziphantsi komhlaba. IIglasi yeprofayileayisebenzi nje kuphela umsebenzi wokukhanyisa kodwa iphinda isebenze njengenxalenye yesakhiwo sophahla, ukunciphisa amacandelo axhasayo kunye nokubonelela ngeeholo zokubonisa ezingaphantsi komhlaba nge-column-free, ingqiqo yendawo.
