Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.云青山和苏岸那边就空闲下来。硝烟烽火起，日寇残暴行，山河破碎，英雄奋起！泪干，血热，不做亡国奴！一场轰轰烈烈的抗日战争，一个个神出鬼没的地雷战场，布下天罗地网，炸的敌人胆战心惊，魂飞魄散！抗战时期的海阳，一群傲骨铮铮的汉子，在中国共产党的领导下，和敌人斗智斗勇，和日寇展开的举世闻名的地雷战！石破天惊，生死缠绵，看英雄地雷传奇，写儿女侠骨柔情…… 河娜的母亲虽然自己的丈夫死了，但还是接纳河娜的姑妈和她的女儿真弥，一起生活。她开了一个小小的温泉浴场，因此认识了经常来洗澡的韩国男人，并打算和这个男人结婚。这个韩国男人就是允书的爸爸。允书在10岁时失去母亲后患上了自闭症，后来因为父亲的再婚，允书和河娜成为法律上的兄妹关系。允书按着十年前因病而去世的母亲的遗言，一下雪就想到母亲回来，因此有了赤脚跑进大雪中的习惯。河娜感觉到允书内心的伤痛后，逐渐接近他。终于让他打开紧闭着的心门，并让他的爱情苏醒。山湾村的胡支书，为讨好本村残疾青年雨生的姑父，当今县里的副县长，应诺一定要为雨生找个好对象。但竟未有一位姑娘肯嫁他。情急之下胡支书找本村青年亮子做了雨生的替身，与杏树洼村的姑娘娟子相亲，心灵手巧的娟子苦于家贫母病，观亮子仪表堂堂便应了亲事......MDT Conference Technology and Equipment之前喊归喊，真端起一碗人肉，军士们都手发颤、心发憷、胃作呕，总之，少有人毫无顾忌地大吃大喝。
