YongJin, YongJin muaj cov qauv tsim nyog thiab cov tsos tshwj xeeb uas tsim los ntawm peb cov kws tshaj lij R & D. Ua los ntawm cov khoom siv raw zoo uas tau sim sijhawm, tshuab weaving, jacquard loom, koob loom muaj qee qhov kev ua tau zoo heev. Ntxiv mus, nws yog ua raws li cov neeg siv khoom xav tau thiab kev lag luam, yog li nws feem ntau ua tau raws li cov kev xav tau ntawm cov neeg siv thiab muaj nqis heev.
Ua tsaug rau peb cov neeg ua haujlwm txawj ntse uas mob siab rau thiab ua tau zoo heev, peb cov thev naus laus zis tau raug hloov kho dua tshiab kom txuag tau ntau tus neeg ua haujlwm thiab tus nqi. Nws cov kev siv tau nthuav dav ntau heev. Tam sim no, nws tau siv dav hauv kev ua haujlwm ntawm Cov Tshuab Ntaus Khaub Ncaws.
Cov thev naus laus zis tuaj yeem ua kom peb cov txheej txheem tsim khoom raug ua kom yooj yim thiab txhim kho dua tshiab, uas txuag tau ntau lub sijhawm thiab lub zog rau peb. Nws qhov kev pab them nqi ntawm daim ntawv thov tau nthuav dav mus rau thaj chaw (s) ntawm YJ-TNF 4/66.
