"Where can you find tofu blocks nowadays?"
"I'll get you some cotton. You can practice tying knots on the cotton; it's the same."
Li Jingsheng got her a ball of cotton.
"When tying knots, you must first ensure that this ball of cotton doesn't move. Because once it moves, it means there's a strong pulling force acting on it. When suturing fragile tissues, it can cause damage or even tear them directly."
He guided Ou Qinglan step by step to improve her knot-tying skills.
"How do I do this?!"
She tried, but found that the cotton moved even before the needle was fully through.
"Tying knots and suturing are actually twin skills, each complementing the other. I'll demonstrate for you."
Li Jingsheng smiled and took the needle holder and toothed forceps from her hand.
"When the needle passes through, you can use the forceps to gently fix the tissue and prevent it from moving. See? No problem passing it through!"
Li Jingsheng performed the suture effortlessly.
