Lethal injections in China who was first?

On July 1, 1997, the legislative committee of the National People's Congress for the first time injection method used for execution of execution in the criminal procedure law of the People's Republic of China. Injection of death penalty in China as to what you say is the first man who don't say that ordinary people don't know, I'm afraid even the supreme people's court were determined. Because legal archives records only so-and-so what year which months which day for what sin was executed without records execution way is injected or shot. Moreover court consider usually executed in order to save costs, etc are concentrated in a batch execution (single executed but rarely), who will deliberately to remember which after the batch execution on death row is the first to perform?
