关于长城建造的历史记载很少，却留下来了很多传说。一些传说甚至把长城建造的过程或技术神话了，有人说垒砌长城的砂浆中含有动物血，还有人说呀，长城墙体之所以坚固是因为在垒砌长城的白灰、沙子中加了糯米浆。这到底是真的假的？

There are few historical records about the construction of the Great Wall, but many legends have been passed down. Some legends even mythologize the process or technology of building the wall. Some say that the mortar used to build the Great Wall contained animal blood, while others claim that sticky rice paste was added to the lime and sand mixture to enhance its strength.Is it true?
