Terai people of Nepal might do "Rangoli" thing, may be in Nepalgunj, Biratnagar, Bhairahawa, Janakpur, Birgunj, etc. There is no doubt that "Rangoli" has Indian origin but we shouldn't be looking down upon it and totally reject the idea. Because, thousand of Indian women get married to Nepalese men in Terai area and they do bring their indian heritage and culture to Nepal and is forwarded to their offspring.
