Water the most powerful force in nature. 2nd grade science. Is this really puzzling to people? What happened to the world? Is there mercury in our water or something?[CN]
水是自然界中最有力量的了。二年级的科学有讲啊。这个真的有那么奇怪吗?这个世界到底怎么了?难道是我们的水中含有汞吗/

. Very interesting! China is amazing for ancient discoveries. May have been used by ancients for farming wild birds like pigeons and their eggs perhaps? I saw walls in the Middle East on ancient buildings that were built to attract nesting wild birds so they could be harvested for food[CN]
真是有趣,中国神奇啊,这么多古老发现。可能是古人用来养野鸟,比如鸽子和它们的蛋的。我在中东有见过很多道墙,建来就是为了吸引筑巢的野鸟,这样他们就可以收获食物了
