Lub Tuam Txhab Zoo Dua

Nyob hauv plawv nroog Cangzhou, Hebei xeev, lub tuam txhab tau ua tus thawj coj hauv kev tsim cov yeeb nkab welded txij li thaum nws tau tsim tsa xyoo 1993. Lub Hoobkas npog thaj tsam ntawm 350,000 square meters thiab muaj cov tshuab thiab thev naus laus zis siab heev los tsim cov khoom lag luam zoo tshaj plaws uas ua tau raws li cov qauv thoob ntiaj teb. Nrog tag nrho cov cuab tam ntawm RMB 680 lab thiab 680 tus neeg ua haujlwm txawj, lub tuam txhab tau cog lus rau kev ua tau zoo hauv txhua yam ntawm nws cov haujlwm.
