After shuffling the tiles, the four of them started playing again.
After discarding two tiles, Lin Xuanxuan's toes lightly glided upward—a glide up meant a demand for character tiles, down for bamboo tiles, and a sideways move for dots.
"Oh, she wants a character tile."
Lin Xuanxuan's foot pressed down on his toes. Pressing the tip meant she wanted a small character tile from one to three, pressing the arch meant a four to six, and moving away meant she wanted a large number from seven to nine.
"Oh, she wants a small character tile from one to three."
Lin Xuanxuan's toes pressed on Su Weifeng's middle toe, the left for one, the middle for two, and the right for three.
"Two of characters!"
This method of signaling was quite straightforward. As long as the signals were remembered, it was very clear what tile the other person wanted.
