Tsis ntev los no, qhov xwm txheej kis thoob plaws hauv lub tebchaws tau qhia txog qhov sib txawv ntawm qhov muaj zog hauv zos thiab ntau qhov kev faib tawm. Nws tau cuam tshuam rau cov khoom siv, kev xav tau, kev xa khoom, thiab kev lag luam ntawm cov khoom lag luam hauv tsev mus rau ntau qib.
Raws li lub Plaub Hlis 8, raws li kev txheeb cais tsis tiav los ntawm Mysteel, tag nrho ntawm 21 lub xeev tau tshaj tawm cov ntaub ntawv tshiab tshaj plaws ntawm kev rov pib ua haujlwm. Ntawm lawv, 19 lub nroog (lub nroog, cheeb tsam) thiab thaj chaw txhim kho (tswj thaj chaw) hauv Tangshan tau tsim kom muaj kev sib haum xeeb.
Tsheb thauj mus los hauv cheeb tsam Handan yog hampered, thiab nws nyuaj rau cov peev txheej txawv teb chaws nkag mus rau Handan ua lag luam, ua rau cov khoom tsis zoo tuaj txog ntawm lub hauv paus. Xuzhou muaj kev tswj xyuas nruj, thiab kev ncig ntawm cov khoom siv hlau yog cuam tshuam loj heev. Gulou thiab Quanshan koog tsev kawm ntawv yog thaj chaw tswj hwm tshaj plaws, thiab cov chaw seem hlau tau raug kaw.(4140 tiaj tus steel)
