"You smart fellow!" Liang Lizheng's eyes held an admiration, "A man appreciating his wife is a good thing. It promotes family stability." Having said that, he dipped the brush lightly in the ink, holding the notebook in one hand and the pen in the other, he walked from one edge of the vacant land to the other. After finishing his walk, he marked the measurement in the book.
He walked in all four directions, each step uniform. When it was not in a straight line, he marked and filled in the distance.
Su Qingyue, watching his movements, quickly understood.
After a long time, Liang Lizheng finally finished measuring, "Let me add it up to see how big the plot is...."
Qingyue faintly said, "The pacing method measures land area. There are ten feet in a span, and ten inches in a foot. A step measures six feet. You've just walked a total of 240 square steps, exactly one acre of land."
