Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim kho kev lag luam, kev tsim kho tau dhau los ua qhov tseem ceeb. Peb pom kev kho dua tshiab txhua qhov chaw, nrog cov skyscrapers nce hauv av. Raws li tib neeg txoj kev ua neej nyob tau zoo dua qub, lawv tau them nyiaj ntau dua rau kev kho kom zoo nkauj hauv tsev, thiab cov khoom siv zoo ib puag ncig tau tshwm sim hauv khw. Yog li ntawd, ntau yam khoom siv hauv tsev muaj kev txhim kho zoo heev. Txhawm rau ua kom tsev zoo nkauj dua, ib yam khoom siv yees siv hu ua "drill wire" tau tshwm sim hauv peb lub neej. Nws qhov tshwm sim tau nyiam kev lag luam ntau thiab tseem nyiam los ntawm cov kws kos duab.
