May 23, volunteers for the 2007 Qomolangma Clean-up Campaign went to the Lhasa Railway Station to provide "Entering Tibet Passenger Environment Protection Promise Card" and environment protection material to passengers to call on passengers to "leave nothing there except footprint and take nothing home except photos".

This activity aims at reducing the pressure to local entironment brought by the increased tourists via the Qinghai-Tibet Railway and calling all the passengers to protect the weak entironment, characteristic scenery and folk custom in Tibet
