EXPERIENCE    i have been to Guilin for class travel.it has been three years that i don’t go to anywhere for travel. i miss the day in Guilin. everything in there was clean including the water, the sky and the moutain. i could see the fish in the river very clearly, i could see the pure sky very clearly even though i didn’t wear glass, i could see the green moutain very clearly from far away. because Guilin is far away from developed area, it has been protected very well for a long time. i hope that everything can remain the same forever.
