Pov tseg thiab cia
Kev ua haujlwm ntawm kev ceev faj: Kev ua haujlwm nrawm nrawm, ua kom muaj zog qhov cua. Cov neeg teb xov tooj yuav tsum tau muaj kev kawm tshwj xeeb thiab ua raws nraim li cov txheej txheem kev ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav lub ntsej muag tus kheej lub plua plav qhov ncauj qhov ntswg, tsom iav kev nyab xeeb tshuaj, polyethylene tiv thaiv kab mob, thiab cov hnab looj tes roj hmab. Txav deb ntawm qhov chaw tua hluav taws thiab kub, thiab haus luam yeeb yog txwv tsis pub ua haujlwm hauv chaw haujlwm. Txav deb ntawm cov tshuaj tua hluav taws thiab cov khoom tawg yooj yim. Zam txhob ua kom muaj plua plav tawm. Zam kev sib cuag nrog tus neeg txo qis. Thaum tuav, thauj khoom thiab thau khoom nrog saib xyuas kom tiv thaiv kev puas tsuaj rau ntim thiab ntim khoom. Nruab nrog cov qib sib xws thiab ntau ntau ntawm cov twj tua hluav taws thiab cov khoom siv kho thaum muaj xwm txheej ceev. Cov thoob ntim yuav tsis muaj teeb meem.
Qhov yuav tau ceev faj: Khaws rau hauv lub tsev khaws khoom txias, kom qhuav thiab cua zoo. Cia kom deb ntawm hluav taws thiab kub qhov chaw. Kev ntim khoom yuav tsum ntim thiab tiv thaiv los ntawm ya raws. Nws yuav tsum muab khaws cia cais ntawm kev yooj yim (sib txuam) sib txuas thiab txo cov kab mob, thiab zam kev sib xyaw sib xyaw. Qhov chaw ntim khoom yuav tsum tau nruab nrog cov ntaub ntawv kom tsim nyog kom muaj cov dej xau.

Cov txheej txheem ntim: hnab yas lossis ob txheej txheej kraft ntawv lub hnab nrog tag nrho lossis nruab nrab qhib cov nruas hlau; hnab yas lossis ob-txheej txheej kraft ntawv hnab nrog lub thawv ntoo zoo tib yam; ntsia hlau-iav saum lub taub hau, lub hau taub hau iav iav lub raj mis, lub raj mis yas lossis lub thoob hlau (tuaj yeem) Cov thawv ntoo zoo tib yam; ntsia thawv-iav sab saum toj lub raj mis, lub taub hau yas los yog lub hau plated steel nruas (cov kaus poom) nrog cov thawv ntim puv hauv av, lub thawv fiberboard lossis lub thawv plywood.
Qhov yuav tau ceev faj txog kev thauj mus los: Thaum caij tsheb nqaj hlau yuav tsum tsim kho nruj raws li cov khoom lag luam txaus ntshai ntawm qhov "Cov Khoom Thauj Khoom Phem Siab" ntawm Ministry of Railways. Nkoj sib cais thaum caij tsheb thauj mus los, thiab xyuas kom meej tias lub thawv tsis ntim, vau, lub caij nplooj zeeg, lossis puas thaum lub sijhawm thauj. Lub tsheb thauj mus los yuav tsum tau nruab nrog cov hom thiab qhov ntau ntawm cov khoom siv hluav taws thaum lub sijhawm thauj. Nws yog nruj me ntsis txwv tsis pub thauj nws thaum uas muaj kua qaub, sib xyaw ua ke, muaj kab mob hauv lub cev, txo cov neeg ua hauj lwm, nthawv cov khoom sib txig sib luag, thiab nplaim taws thaum ntub. Thaum thauj khoom, qhov ceev yuav tsum tsis txhob nrawm dhau, thiab hla dhau tsis tso cai. Cov tsheb thauj khoom yuav tsum tau ntxuav kom huv thiab ntxuav ua ntej thiab tom qab thau khoom thiab thau khoom tawm, thiab nws yog txwv tsis pub tov cov organic, cov teeb meem thiab lwm yam tsis txaus.
