This article is an empirical research on the current constitutional review system and other activities with the significance of constitutional review in China. The research is a response to two assertions：the first is that there is no practice of constitutional review in China；the second is that the criticism against the constitutional review system in China is groundless. This author of this article holds that，although a constitutional review system has already been provided for in the Chinese Constitution and laws，there is no constitutional review practice in the standard sense. On the other hand，there exist within the current institutional framework some legislative and judicial activities that meet with the logical criteria of constitutional review. Such practices，if give extended application，may over time provide practical and institutional bases for the establishment of a standard constitutional review system in the future. Therefore，the existing constitutional review activities in China can be defined as a kind of quasi-constitutional review，which can be gradually standardized through political and legal practice.
