I was very amused to learn that south-asians like Koreans and Japanese make a great deal out of blood types.我很有趣地獲悉，南方亞洲人一樣，韓國和日本作出了大量出血型。 Apparently B types are bad boys, yeah!顯然是B型是壞的男孩，是啊！ Wait, it gets worse.等待，這進一步惡化。

In south-Asia (India excluded), the subject of linking blood types to personality took off with the 1927 publication of a series of articles by Japanese scholar Takeji Furukawa called “The Study of Temperament Through Blood Type.”在南-亞洲（印度除外） ，題目聯繫起來的血型，以人格的起飛與1927年出版了一系列的文章，由日本學者takeji古河所謂的“研究的氣質，透過血型” 。

The concept hit pop culture and mass media in 1971 when Japanese writer Masahiko Nomi expanded upon Furukawa’s ideas and wrote “Understanding Compatibility from Blood Types.”的概念，擊中流行文化和大眾傳播媒介在1971年時，日本作家昌彥nomi擴大後，古川的想法和寫道： “了解相容性，從血型” 。

Type-O people were described as outgoing, expressive and passionate .類型- O的人被描述為即將離任的，具有表現力和激情 。 Type-A were considered introverted perfectionists while type-AB were an unpredictable, distant lot . A型被認為是內向，完美主義 ，而類型- Ab的一個不可預知的，遙遠的很多 。

And then there was type-B.然後有B型血。 They were considered independent spirits with strong personalities .他們被認為是獨立的精神與強烈的個性 。 That exactly matches my personality這完全符合我的個性 ： ）

However the cultural stereotypes projected are much worse.不過，文化成見，預計差得多。 There are many characteristics associated with type-B people, but the bad rap going around about type-B men in Korea is that they are selfish, mercurial and absolutely useless as caring and devoted boyfriends.有很多特點，與B型血的人，但壞的說唱繞過有關B型血男人在韓國是他們自私，汞和絕對無用的，作為關懷和專門男朋友。 Personally I am not selfish even by the most restrictive definition of the term, but I don’t know the part about “caring and devoted boyfriends” because I never (this is not a typo) ventured into dating scene.我個人不自私，甚至限制最嚴的一詞的定義，但我不知道的部分，關於“關懷和專門男朋友” ，因為我從來沒有（這不是一個錯字）冒險涉足約會現場。

According to a nationwide survey in South Korea conducted by Internet portal site xyinlove.co.kr, type-B men were considered to be the most difficult type to date and about 40 percent of women said they did not want to marry a type-B man.根據一項全國性調查，在韓國進行的互聯網門戶網站xyinlove.co.kr ， B型血男人被認為是最困難的類型，日期和大約40 ％的婦女說，她們不想結婚， B型血男人。 Source來源

So if you are in Korea and you are type B and you intend on dating Korean women then be sure not to reveal your blood type or better yet say A (all is fair in love and war).因此，如果您是在韓國和你是B型和你打算對約會的韓國女性，然後千萬不要透露您的血型或更好，但說（全部是公平的，在愛和戰爭） 。 I wonder if they will go as far as requiring to see your blood test report before saying “Yes” to your bended knee proposal.我不知道，如果他們將據需要看到您的驗血報告，然後說“是”您的膝關節彎曲的建議。
