After Baikal teals(Scientific name: Anas formosa) get through winter passing through the mouth of Han River
and the bay of Cheonsoo, Choongcheong nam-do to Dongrim reservoir, Gochang, Jeolla book-do, and Joonam reservoir,
Changwon, Gyeongsang nam-do, South Korea, they migrate northward next spring. 90 percent of Baikal teals over the
world get through winter in the Korean Peninsula.
A flock of Baikal teals wheels round in the air making a group dance. One form of a group dance resembles a big whale, one form of it is like a roc, and the other one is similar to the clouds. Truly, these are a big whale, a roc, and the clouds respectively! No.
Pinmulihuang牝牡驪黃 is said that as follows in Lie Zi列子·Shuofu說符:
When Mugong穆公 in Qin(ancient nation of China B.C 221-B.C206) let Jiufanggao九方皐 search for a horse by recommendation
of Bole伯樂, Mugong穆公 made someone bring it to him as it was reported that Jiufanggao九方皐 found a brown mare. Mugong穆公 scolded
Jiufanggao九方皐 that the horse's body color and the sex of the horse could not be distingished. Bole伯樂 said a seeing of Nature's
mystery is needed in choosing a horse being undeterred by vestiges. That is, one's real worth is more valuable than one's
looks. It is essential to grasp the essence in understanding a thing.
가창오리는 우리나라의 한강 하구와 충남 천수만을 거쳐 금강 하구, 전북 고창 동림저수지, 경남 창원 주남 저수지 등에서 겨울을 난 뒤 이듬해 봄 북상하는데 전세계 가창오리의
90%가 한반도 남쪽에서 겨울을 난다. 가창오리떼(Baikal Teal: Anas formosa)가 하늘을 날면서 군무룰 하는데 어떤 것은 그 형태가 큰 고래를 닮았고 어떤 것은 붕새를 닮았고
어떤 것은 구름을 닮았으니 정녕 이것이 큰 고래요 붕새요 구름인가! 아니다.
