明太祖朱元璋一生傳奇，風流韻事也不少！幼時貧窮的朱元璋，曾為地主放牛，做過乞丐、當過和尚，最後竟成為明朝開國皇帝；而他的精彩人生還不只如此，在還未成為皇帝前，他加入起義軍到處征戰，曾因戰敗躲到寡婦家，沒想到竟跟寡婦發生了關係，兩人還許下了山盟海誓，成就了一段佳話！
broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.朱元璋25歲時參加郭子興領導的紅巾軍起義反抗元朝，入伍後作戰勇敢，機智靈活，打仗時身先士卒，很快成了郭子興的心腹大將，郭子興見朱元璋是個人才，還把養女馬氏嫁給了朱元璋；不過，驍勇善戰的朱元璋，再怎麼厲害，也不可能場場都打勝仗；不料，有一次打了敗仗落荒而逃，逃到了一個寡婦家，寡婦好心地安頓了朱元璋，讓他避開了追捕者，並細心照料；朱元璋見寡婦頗有姿色又溫柔，寡婦也見朱元璋英雄氣概，兩人互有好感，乾柴烈火於是發生了關係。

在溫柔鄉待了數天後，隨著戰爭告一段落以及追捕者的消失，朱元璋決定離開。然而，幾天下來，兩人已有了感情，且還有了夫妻之實；因此，在朱元璋要離開時，寡婦就問朱元璋，如果她意外懷孕了要如何處理？面對寡婦的問題，朱元璋也很真誠，他可不想成為負心漢，他隨即拿起桌上的木梳，把它對折，留下一半給寡婦作為信物，並表示，如果她懷孕了，可以拿著信物找他，他絕對會負責到底。

後來，朱元璋的仕途順風順水，一路攀升，最終成為明朝的開國皇帝，史稱明太祖；說來也巧，這個寡婦後來真的懷孕了，因為她是一個寡婦，寡婦懷孕怎能隨便求助於人，那豈不是漫天流言蜚語；所以，她就拿著梳子去找朱元璋，朱元璋雖然感到意外，但並沒有矢口否認，仍負起了責任，為母子倆在宮外建造了房子，安排人照顧她們，將孩子賜封為代王，取名朱桂，寡婦封為郭貴妃。
