Tobuildsuchanenormouswallacrosssuchwildandmountainouscountrywithoutanymoderntractorsorotherheavymachineswasverydifficult.AlltheEmperorsbuilderswerethousandsofmen,oftenprisonersofwar.Theyliftedtheearthinbucketsanddraggedthestonesinteamswithropesovertheirshoulders.Theyworkedinsuchwildanddistantplacesthatitwasdifficulttosupplythemwithenoughfoodortomakepropersheltersinwhichtheycouldsleep.Thousandsofworkersdiedandwereburiedintheclayinsidethewall.ThepeoplehatedtheEmperorforhiscrueltybuthemadethemfinishthewall.Manypeoplewereseizedandforcedtoworkonthewallfarawayfromtheirhomes.Manyofthemnevercameback.

2.TheYellowCraneTower
OnMay20,1985thenewly-rebuiltYellowCraneTower(HuangheTower)wascompletedandopenedtothepublic.
Therebuildingofthetowertookfouryearsandcost15millionyuan.
Thisfive-storeyedbuildingstandsonthetopoftheSnakeHill(MountShe)bytheChangjiangRiverinHubeiProvince.Itis51.4metreshigh.Inthehallsofthefirstfourstoreystherearemanypictures,portraitsandwall-paintings.Theyareaboutfairytales,Chinesehistoryandthehistoryofthetower.
Doyouknowwhenthetowerwasfirstbuilt?Andwhydowecallit“TheYellowCraneTower”?
ThereisalegendthatlonglongagoanoldmannamedWangZhianrodeonthebackofayellowcrane,flewawayfromthetowerandlaterbecameanimmortalbeing.ItisalsosaidthatanothermannamedFeiWenyireturnedtothetowertohavearestwiththehelpofayellowcrane.

However,beforeliberation,theYellowCraneTowerwasnotwellprotected.WhenWuhanwasliberated,onlyaveryshabbytowerremained.
