Q: CQC TRACK nyob qhov twg?
A: CQC TRACK nyob hauv Quanzhou, Fujian Province, Suav teb—ib lub koom haum kev lag luam tseem ceeb rau kev tsim khoom siv tshuab nrog kev nkag mus rau cov chaw nres nkoj loj thoob ntiaj teb rau kev faib khoom thoob ntiaj teb zoo.

Tsab ntawv tshaj tawm txog kev siv tshuab no yog rau cov thawj coj khoom siv tshaj lij, cov kws tshaj lij kev yuav khoom, thiab cov neeg ua haujlwm txij nkawm hauv kev ua haujlwm khawb av thiab kev tsim kho hnyav. Cov lus qhia tshwj xeeb thiab cov lus pom zoo yog raws li cov qauv kev lag luam thiab cov ntaub ntawv tsim khoom muaj thaum lub sijhawm tshaj tawm. Yog xav paub txog cov kev cai thov tshwj xeeb thiab cov lus qhia tam sim no ntawm cov khoom, thov nrog CQC TRACK pab pawg engineering tham ncaj qha.
