In a small village in Northeast China, there was an old blind woman called Grandma Liu. Although she could not see, she had a very kind heart. Whoever came to her for help, she would happily help them. She had a neighbor called Aunt Sun. Aunt Sun had many children at home, so she often went to borrow rice and flour from Grandma Liu, and every time she did so, Grandma Liu would happily lend it to her, even trusting her to measure it out herself.
Every time Aunt Sun filled the container with rice or flour, before she left, she would let Grandma Liu touch the rice to let her know that the rice inside the container was at the same level as the rim of the container. When she returned the rice, she would do the same: take it to Grandma Liu and let her touch the rice in the container. Gradually, the process had become a routine for Aunt Sun.
