Q:red-crowned cranes....?

Normally the crane lays 2 eggs, with only one surviving. Later, in the fall, it migrates in flocks to Korea, Japan, China, Taiwan, and other countries in East Asia to spend the winter. All Red-crowned Cranes migrate, except for a flock that is resident in Hokkaidō.
Q:I'm writing a story on kung-fu and I need some info on the White Crane fighting style.?
The Fāng family lived in Fujian, a province of China, in a place where there were many cranes. Qīniáng's father knew the Southern Chinese martial arts and taught them to his daughter. One day, while Qīniáng was doing her chores, a crane alighted nearby. Qīniáng tried to scare the bird off using a stick and the skills she learned from her father but whatever she did, the crane would counter. Qīniáng tried to hit the crane on the head, but the bird moved its head out of the way and blocked the stick with its wings. Qīniáng tried to hit the crane's wings, but the crane stepped to the side and this time blocked with the claws of its feet. Qīniáng tried to poke the crane's body, but the crane dodged backwards and struck the stick with its beak. From then on, Qīniáng carefully studied the movements of cranes and combined these movements with the martial arts she learned from her father, creating the White Crane style of Fujian Province. A side note from someone else: There are many versions of this legend, it is unlikely that the crane actually blocked the stick Qīniáng used, it is more likely that it evaded, and countered. The point of the style is to make less use of physical strength, stressing evasion, and attacks to vulnerable areas instead. Not depending on strength, is what makes white crane fitting elements so popular, especially for women’s self defence. Popular karate bunkai (breakdown) of white crane katas like hakutsuru, stress vital point striking or kyusho. The white crane system is not practiced much, if at all, anymore. There are several kata in karate, that have white crane elements, most stem from the Chinese tea merchant on Okinawa, Go Kenki, but few, if any, have the true white crane system anymore. There's also a tibetan style and a karate style named after it that strongly resembles it and incorporates much of the same methods.

Q:Have you studied Tiger and Crane Kung Fu? ?
i aint trained in kungfu but i have studied it... im a karate practitioner and abit of a boxer. one day i was bored and looking up martial arts then i came across kungfu... it was very interesting looking it up. Theres over 300 styles of kungfu. some styles of kungfu represent a animal. For example... you got crane kungfu... if you know what a crane is, its a type of bird... strong on its legs, well balanced... goes with the flow, elegent. Crane kungfu practitioners have strong perfect balance... just like the crane. You got snake kungfu... just like a snake, it looks at there prey and attacks very accurutly... the speed of the snake bite is so fast, you might not even see it coming. So with snake kungfu practitioners... they are swift like a snake, smooth... Theres tiger kungfu... just like a tiger... vicious, focused... they attack there prey, strong... hard. Theres monkey kungfu... not sure about that one. but thats some styles i know... theres other styles like jeet kun do (the way of the intersepting fist)... drunken boxing ect... this is some of what i know... oh yh theres anouther style called the praying mantis... looks very good. so inconclusion... most of the animal styles of kungfu represent the animal in a certain way... which makes kungfu spark out for me. hoped this helped :)
