Ha ly is an experienced monk. It can dig a steep inclined tunnel into the river, on the shore of the large living creatures with a variable water level, and a tunnel of about 1m wide, 0.5m high. Each house has about 2 or more access tunnels, tunnel mouths are underwater. The upper part of the cellar is the resting place of the lyre, the place adjacent to the water is the "dining room", for convenient cleaning and also for convenience.

If the water is up, the galaxies will dig up the high ceiling, taking the soil to elevate the floor. If you feel the ceiling is too thin, it will reinforce by covering the soil or installing small branches. If the water continues, it will make a floating wooden house to live in, surrounded by water. Ha Ly can be built into a small island with tree branches and bark floating up to 2-3m. Floating houses also have entrance entrances. The entrance is all underwater. Ha Ly carefully took the mud into the wall, but he never forgot to ventilate the house.

Ha Ly is also a "water works master" who knows how to beat water and regulate water levels . They work collectively, with wood in their teeth, taking the previous limb and moving the timber into the river, pushing it to the designated position, then cutting into wooden sections that are closed to the riverbed vertically to make a pile, then take the big branches over. on and take the fork against the bottom. If the dam is very wide, take the stone to reinforce it. They take reeds, grass and small branches and soil into the gaps, causing the dam to not leak. In the middle of the ever-peaking dam, the lychee is also taller than the two sides, what a marvelous work. The completed dam will make the water above the quieter flow, like a lake, enough depth for the swimmers to swim there, and become their home.
