古人常说:学得文武艺,卖与帝王家。这个“卖”就是推销。一个人如何把自己推销出去,让别人承认自己的价值,这是一门学问。一千多年前的京城长安,一个年轻人孤独地徘徊在大街上,他非常愤懑,自己一肚子才华,可来长安半年了,投靠了无数显贵,竟无人赏识自己。真是怀才不遇呀! Ancients often say: learning martial arts, selling and imperial family. This “sell ” is selling. How to sell yourself to others, let others recognize their own value, this is a learning. A thousand years ago in the capital of Chang’an, a young man wandering alone in the streets, he was very angry, his belly talented, can come to Changan for six months, to countless dignitaries, no one actually appreciate themselves. Really underappreciated ah!
