Wildlife occupies an integral place in the ecosystem. The inestimable values of wildlife are arresting more and more attention in di!erent domains such as ecology, genetic engineering, sociology, economy, science, education, culture, entertainment and aesthetics. The need to protect wildlife worldwide has achieved global concern and it demands commitment from the whole society. Furthermore, tireless efforts have been made by the international community in the field of wildlife protection. However, wildlife trade keeps cropping up all over the world, which tells heavily against current efforts, thus gravely disrupting the order of rational wildlife utilization, resulting in resource depletion and endangering many animal species. In response to such a grave situation, it is imperative that we cope with these issues preemptively.
