How to repair the water at the bottom of the tent?
It's not a good tent. If you change it, remember to use cloth, especially when you're camping on the rubble.
If you must fill, fill the outdoor shop sell tents suit, is actually a piece of plastic cloth (old umbrella or broken backpack cover) and a tube of AB glue, can also be made. You take a piece of traumatic emergency plaster with a lighter baking heat is stamped on the outside in the gap. No matter how you do that, remember to wash and clean the place where the tent is broken.
