This knot is said to be the very simplest one to tie, because of its relatively few moves. The knot is popular among Chinese teens, hence it's name. The knot is suitable with wool and thicker ties, and is a symmetric knot.
Drape the tie over your neck, with the reverse side out - the inside of your tie facing outward - and the wide end on your right side.
Cross the narrow end of the tie over the wide end.
Wrap the wide end of the tie back over the narrow end, from left to right.
Pass the wide end of the tie under the narrow end and bring it up through the center of the loop around your neck.
Bring the wide end down through the loop in front
Gently tighten the knot by pulling down on the narrow end and sliding the knot up to your collar. (Refer Step 6 and 7)
