On the fourth day, Li Younan finally managed to construct the main structure of the house. Next, he needed to lay down rafters on the roof, the sloped layer beneath the tiles.
With the rafters installed, he could lay thatch, waterproof cloth, or, if feeling a bit luxurious, even tiles on top.
It's worth mentioning that Li Younan was selective about the wood he chose. The main framework of the house used another advantageous tree species found around the lake, the white spruce and black spruce. These trees have tall and straight trunks, with wood that is light and tough, easy to cut and split, and naturally resistant to decay, making them ideal for the shelter's posts, beams, rafters, and other core framework.
To facilitate working at heights, Li Younan took some time in the afternoon to make an A-frame ladder for himself, also using the mortise and tenon structure.
