III. Environmental Benefits thiab Social Contributions
Kev ua tiav ntawm qhov chaw kho dej khib nyiab no tau txhim kho cov dej hauv nroog hauv nroog Xi'an tau zoo. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj cov pa phem, tiv thaiv cov dej zoo ntawm cov dej hauv zos, thiab tswj kev sib npaug ntawm ecological equilibrium.
