A lungi is a traditional garment worn by men in South Asia and parts of Southeast Asia. It is similar to a sarong and is worn wrapped around the waist. Here is a basic step-by-step guide for tying a lungi:

1. Start by draping the lungi around your waist, with one end slightly longer than the other.
2. Take the longer end of the lungi and bring it up and over your left shoulder, tucking it into the waistband on the right side.
3. Take the shorter end of the lungi and bring it up and over your right shoulder, tucking it into the waistband on the left side.
4. Take the shorter end of the lungi and bring it up and over your left shoulder again, tucking it into the waistband on the right side.
5. Take the longer end of the lungi and bring it up and over your right shoulder, tucking it into the waistband on the left side.
6. Adjust the lungi as needed to ensure it is snug and sitting properly on your waist.
7. Take the remaining fabric and drape it over the left shoulder or bring it to the front and tuck it in the waistband.

Note: There are many different ways to tie a lungi, depending on the region and cultural customs. This is just a basic guide to help you get started. It may require a few attempts and practice to get the hang of it.
