Sending an open letter, Li has heavily criticised Beijing's decision.

"As a Chinese citizen, I have to fulfil my responsibility and tell the delegates my opinion. I don't care what these delegates will do. It's not like the whole country agrees with the amendment, but everyone has been silenced," he told BBC Chinese.

The former editor said that he and his friends were enraged and had to voice their opposition.

"In theory, NPC delegates from Beijing have to represent the several million voters in the capital. I am a voter and I write a letter to the delegates representing me. I express my opinion on the amendments. It is very safe legally," he said.

Even if the amendment is passed, it doesn't matter. History is often like this - we make two steps forward and one step back. But this is against the tide of civilisation and won't stand the test of time. It will be considered a farce in Chinese history in the future," the critic added.

Others have called the move a betrayal.

The criticism comes at a time when the state media have been praising the move as 'necessary and timely'.

Chinese internet censors have been deleting harsh and critical comments pertaining to the issue on social media.

Xi has already established himself as a peerless politician in China.

His recent rise has had commentators comparing him with the great Mao Zedong.

According to the norm, his presidency would have ended in 2023, but the government has decided to facilitate an endless run for him.
   
While China has witnessed economic reforms and a crackdown in corruption under his Presidency, Xi is also known to tackle his critics in a harsh way.

During his tenure so far, he has riled several human rights groups.

Xi's extension is a matter of approval from the NCP, which will begin its annual meeting from Mar 5.

According to commentators, Xi, who has gone unopposed thus far, is likely to continue.
