How to understand the organizational form of political power in China?

The argument that the principle of the distribution of powers in China is that the combination of discussion and execution was once the orthodoxy. It was deemed as the fundamental difference of the socialist constitution and capitalist constitution. But in practice, the power of legislation, the power of administration and the power of adjudicatory are distributed to different branches. The orthodoxy is challenged. However, the separation of powers seems not a choice, as it had been excluded by the former chairman of the Standing Committee of the National People’s Congress officially.

Then how to understand the organizational form of political power in China? This paper will try to answer the question, based on the interpretation of Article 3 of the Constitution of China.
