Most of the stone implements found in the Liang Zhu Culture are tools, which are carefully made, with sharp blades and also show sophisticated skill in the hole drilling. All of these stone artifacts are of a unique style. There is a complete set of agricultural tools. The stone plough is as long as nearly 50 centimeters, with a thickness of 1.2 centimeters.
