Yun Jiao said to Zhang Shun and Liu Zhu: "You two pay attention, the fire shouldn't be too strong. If it's too strong, the water will evaporate quickly, but it also can't be too weak, otherwise, the glue won't come out."
She pointed to the iron pot and said: "Just keep the water in this just-boiling state."

Lao Jiu, beside him, winked at Jiang Youzhi, "You're still young now, you don't need this. When you're over fifty, you'll know how good this stuff is."
