My school team is invited to two events in Beijing and Tianjin. Is visa form as of last year?

I know the visa forms as from 2006 to 2011, but I heard that the Authority have changed the forms. Could you be of help to assist on that.

We are invited to attend the Great Wall Youth Football Tournament in Beijing, and later The Tianjin International Youth & Children Art and Culture Festival - Tianjin.

We have been visiting China and North Korea every Summer from 2006 to date. We are in Morogoro town, four hour drive from Dar es salaam, so through this, we can find the answer before we drive to Dar, all we need is to go to the Embassy with all what they need.
