Similar to the development of children from appearance and color to older children, they can be classified according to concepts. For example, if they know the concept of "food", no matter what kind of vegetables they look like, they should be classified into one category. The classification of biology has also developed in this way. The earliest method is to identify and distinguish species according to phenotypic characteristics, and to classify them step by step according to the degree of phenotypic similarity, so as to establish a classification system that is easy to retrieve. This is the principle of phenotypic classification. However, the problem of phenotypic classification is that it is difficult to reveal the essential laws of things. Many creatures with very different shapes may have kinship relationships. For example, the online sentence "When I knew sunflowers belonged to Compositae, I collapsed" is what it means.Surname is a sign and symbol that indicates a person's family and blood relationship. The descendants of the same ancestor are called clans. Surnames originated from the name of the tribe or the name of the tribal leader. Its function is mainly to distinguish the descendants of different clans in the tribe and to facilitate intermarriage between different clans. Therefore, the emergence of surnames marks the change from group marriage to blood marriage and is an important milestone in the progress of human civilization.《爱上试睡师》是由青年导演罗登指导 ，丹尼斯吴 、唐婧、肖旭主演，曾江等老派实力演员加盟的一部爱情喜剧电影。该片主要讲述了患有多年“失眠症”的试睡员罗潇潇因工作关系入住一家酒店，与冷漠、不得志的酒店集团公子相识，在针锋相对的过程中，两人渐渐相知相爱，同时，罗潇潇发现，“睡不着”的人不止她一个……一幕幕引人发笑又引人深思的故事正在这个五星级酒店陆续上演。TOP集团的长孙、帅哥栋奎亲自驱车探访济安李氏宗家花安堂的真面目。哦，真是该死，怎么不溜神把骑车的人挤下了马路？嗬，竟是一位身着韩服、裙裾飘飘的美丽小姐，情窦初开的栋奎砰然心动。接下来的事让栋奎大跌眼镜，这位看起来古怪精灵的女孩竟然是他要找的花安堂的主人、宗家小姐李秀荷！怎么办？会长爷爷有话：拿到花安堂的孙子才可以接管TOP集团。对于两耳不闻窗外事，一心只学经营术的栋奎来说，接掌TOP集团具有不可抵挡的诱惑力。栋奎决定无论如何一定把花安堂拿到手！爷爷何以对花安堂情有独钟？原来会长大人50年前只是花安堂的区区一长工，一个月黑风高的夜晚，他赶着驮了一袋大米的老牛从花安堂逃出，后来才有了今天的叱咤风云。昔日辉煌的宗家花安堂虽然看上去依旧宏大威严，其实已日趋破落。不过它可是秀荷心目中的宝贝，卖它？绝对不可以！饱受传统教育的秀荷也并不甘心只做花安堂守护者，她要到大都市闯闯天下。谁说都市里只适合红男绿女？秀荷带着乡间的淳朴、挟着传统的威力，在现代的都市里横冲直撞，竟也所向披靡……这不？TOP集团的另Foul play is suspected when an apparent suicide victim still has the gun in his hand, and a flower delivery woman is found crushed to death in the middle of a Cirque du Soleil performance.强兵，究竟是天生的还是练出的？凶狠亡命的特质，与遵从指挥的军纪是否能够合二为一？只有实践才能证明了。板栗觉得自己掉进了一个早就预谋好的大坑。
