Ra Nong Nu heaven after several years, appeared on earth and a great God. He and his great-great-Vulcan Vulcan govern together with twelve thousand miles south of the earth, and to dominate the life of the South.
Yan is a Ci Airen thick great God. When he was alive, human beings on the earth due to the ongoing lives and breeds, nature of food production has been insufficient to meet people"s needs, so, caring Yandi will teach how humans sowing and harvesting grain, with their own hard work to in exchange for all of life needs.
When he wants to teach the human germ grain from many kinds Sky Valley have landed, he gathered up the valley to the species, have been sown on reclaimed land. Once, he saw a bird covered in red, mouth title of a Spike nine seedlings from flying in the air, fall to the ground grain on the ear, Yan put picked them up to the kinds of fields.
After these grains grown, people eat can not only eat, but also to live forever. With enough food from humans, life is very stable.
At that time, humans working together, helping each other, neither masters nor slaves, harvest the fruit evenly distributed, people"s emotions like a general personally close enough.
In order to allow human beings to live a happier life, Yan letting enough light and heat emitted by the sun, so that more grain grow well, so that people living in the bright warm light in. Since then, mankind no longer worry about food and clothing, people are very grateful Yandi kindness, they called him Shennong. According to legend, Emperor look is head of a cow, it is probably that his contribution is inseparable.
Sunlight is a healthy source. Therefore Nong god of agriculture, is also the god of medicine. Yan has a whip, known as ocher whip. He used this root whip a variety of herbs, through a variety of medicinal herbs ocher whip whip, toxic or non-toxic cold or hot it is clearly presented. So he depending on the potency of these herbs to saving lives. In order to determine more potency, he also personally herbs to taste. To taste the medicine, he was poisoned in one day many times in his seventies. Once he tasted a highly toxic Gelsemium elegans, it is now being broken rotten intestines.
Yan see the human though clothed, but in life but there are a lot of inconvenience, so letting people set up a trade market, need each other to get things up exchange market. In the market, available-for-grain hide, or pearls exchange axes and the like. With this exchange, the more rich people"s property up. Was no clocks, no other method of recording time, people can not put down the live long day waited at the market to determine what time to exchange it so, Yandi and a method to teach people, when the sun shines on the people when on the head, you go to the market to trade, after a period of time, it will automatically leave the city also scattered. At the time, people are put into practice, it feels easy and accurate.
In Yandi education, his descendants also made many contributions to mankind. Shu as his grandsons made archery arrows, targets, drums and Ting, also produced a musical instrument called the bell, and later, through the efforts of both of them, wrote many songs, make music in the world is widely popular.
太阳神炎帝是女娲升天若干年以后，出现在大地上的又一位大神。他和他的玄孙火神祝融共同治理着南方一万二千里的大地，主宰着南方的生命。
炎帝是一位慈爱仁厚的大神。当他在世的时候，大地上的人类由于不断的生息繁衍，自然界生产的食物已经不足以满足人们的需求了，于是，仁爱的炎帝便教给人类如何播种和收获五谷，用自己的辛勤劳动来换取生活所需要的一切。
当他要教给人类种五谷时，从天空纷纷降落下许多谷种，他收集起这些谷种来，播种在已经开垦出来的土地上。一次，他看到一只浑身通红的鸟，嘴里衔了一株九穗的禾苗从空中飞过，穗上的谷粒落在地上，炎帝便把它们拾起来种到了田里。
这些谷物长成后，人们吃了不但可以充饥，而且还可以长生不老。人类从此有了足够的粮食，生活非常安定。
那时候，人类共同劳动，互相帮助，既没有主人，也没有奴隶，收获的果实大家平均分配，人们的感情像亲手足一般亲密。
为了能让人类过上更加幸福的日子，炎帝又让太阳发射出足够的光和热，使五谷更加茁壮地生长，使人们生活在灿烂温暖的光明中。从此，人类再也不愁衣食，人们非常感谢炎帝的恩德，便尊称他为 神农 。相传炎帝的样子是牛头人身，这大概与他的这一贡献是分不开的。
太阳光是健康的源泉。因此炎帝是农业之神，同时又是医药之神。炎帝有一根神鞭，被称为赭鞭。他用这根鞭子抽打各种各样的药草，药草经过赭鞭的抽打，有毒无毒或寒或热的各种药性就很明显地呈现出来。于是，他就根据这些药草的不同药性来治病救人。为了更加确定药性，他还亲自去品尝百草。为了尝药，他曾在一天里中毒过七十多次。一次，他尝了一种有剧毒的断肠草，竟然被烂断了肠子。
炎帝看到人类虽然丰衣足食了，但在生活上却还有诸多不便，于是又让人们设立了贸易市场，把彼此需要的东西拿到市场上来交换。在市场上，可用五谷换兽皮，或用珍珠交换石斧等。有了这种交换，人们的财产就更加丰富起来了。那时没有钟表 ，也没有其他记录时间的方法 ，人们又不能放下手中的活整天守在市场上，凭什么来确定交换的时间呢 于是，炎帝又教给人们一个方法，当太阳照在人们头顶上的时候，就到市场上去进行交易，过了这段时间，大家便自动离去，也就散市了。在当时，人们实行起来，感觉既简便又准确。
在炎帝的教育下，他的后代也为人类作出了许多贡献。如他的重孙殳制作了射箭用的箭，靶，鼓和廷，又制作出了一种叫钟的乐器，后来，他们两人又经过努力，创作了许多歌曲，使音乐在人间得到广泛流行。
