In preparation for the big military parade in Beijing on October 1, thousands of PLA troops have been practicing and drilling for months (maybe years). The photo below is taken at one of the training bases near Beijing. The sign on the wall is in classic Communist literary style–a four part slogan in exact parallel structure.
The slogan roughly translates as this:
Sit for four hours and don’t move;
Stand for four hours and don’t fall.
Blow for four hours and don’t get tired.
Hold for four hours and don’t urinate.
For the glory of the Motherland, don’t pee!
