China adds "religion" to constitution

I recently read a article on the website chinanews.cn, that the word religion has been added to there constitution during the recent 17th CPC National Congress.

I don't read the Chinese language that well, so understanding the full context of adding the word religion to the constitution is not in my knowledge. I do think that China is trying to allow more religious freedom, but as long as there are crackdowns on illegal churches, then China has a long way to go to "really" having freedom of religion.
