The setting-out of Sapporo City is just like a checker board with the streets running most in the north-south and east-west directions and numbered in an orderly fashion. 饭后继续行程，沿途风光美丽。下午三时许，我们到达‘拓真馆’,馆内展览着几百幅北海道一年四季的摄影图片。
A checker slides orthogonally or diagonally until stopped by an occupied cell or the edge of the board. 一子在阴线或阳线上滑动直到碰到其他子或者边界.
Peter waving a checkered flag as he passes! 真是一段不可思议的预言。
