After that, Jiang Yue and Xue Yan added the liquid that had cooled down into the bamboo tube. When the bamboo tube was 80 percent full, Jiang Yue picked it up and knocked the bottom of the tube on the stool to make sure there was no gap between the liquid.
Some of the liquid had been used to fill the gaps at the bottom, so the bamboo tube was not 80 percent full. Therefore, Jiang Yue and Xue Yan added more liquid into the bamboo tube, making it 80 percent full again.
She then knocked the bottom of the bamboo tube lightly before placing it into a large basin that had been prepared.
The big basin was already filled with river water, and it was also 80 percent full.
The bamboo tubes were not as tall as the big basin, and bamboo had a certain buoyancy. Not only was it very stable to put ten bamboo tubes in, but the liquid in the bamboo tubes was also lower than the water level in the big basin, which was just right.
