You can say whatever you like and want to say.
You can blame everything wrong on the party.
If the party is so bad, however, over 60% people are bad too ar least.
Because the party is formed by your brother, your sister, your mother, your father, your relatives.......etc.
If you can not change the party, which means everybody has a little bit of problem to hold up the country too hard to change.
If you like to change China, Change yourself first.
China will have its own dream, that is different from US dream with Chinese style.
