Help Hong Kong people to have the election of CE that meet the international standard

We, Hong Kong citizens want to choose the Chief Executive on our own. But the Hong Kong government and the PRC government ignored the wants of us.
Now the students are having the class boycott, but the government officials are all disappear and keep on ignoring the Hong Kong citizens.
The polices even use violence means to attack the students.
Hong Kong is really in trouble now. We just want to express our opinion, have our own rights, but the government is starting to take the freedom from us.
I really hope that the US government can involve in it to help us to get our basic human rights.
