Here is a video explaining how to tie the Oriental knot.
From Wikipedia:
The small knot, or oriental knot, is the simplest method of tying a man’s necktie, though some claim the simple knot is an alternate name for the four-in-hand knot. The small knot is not very well-known despite its simplicity. One of the reasons may be the fact that the small knot is not self-releasing, and may annoy people accustomed to four-in-hand and Windsor knots who pull at the tie to untangle the knot. Additionally, some prefer that, if the thin end of the tie should become visible, that it not be “inside out,” and the small knot will be this way (this can be remedied by twisting the tie one half turn while tying).
The Windsor-knot, also sometimes referred to as a Full Windsor or a Double Windsor to distinguish it from the half-Windsor, is a method of tying a necktie around one’s neck and collar. The Windsor knot, compared to other methods, produces a wide triangular knot. The knot is often thought to be named after the Duke of Windsor (King Edward VIII before his abdication). It is, however, named after his grandfather Edward VII. The Duke preferred a wide knot and had his ties specially made with thicker cloth in order to produce a wider knot when tied with the conventional four in hand knot. The Windsor knot was invented to emulate the Duke’s wide knot with regular ties. The Windsor knot is worn on more formal occasions, and it is especially suited for a spreadcollar that can properly accommodate a larger knot.
