New Delhi: Prime Minister Narendra Modi said on Sunday, ending people's curiosity about the stick-like object he held while jogging on Mamallapuram beach, it was an acupressure roller he often uses. Modi was in the coastal town with Chinese President Xi Jinping for a two-day informal summit. During his morning walk, the Prime Minister was seen cleaning up a beach on Saturday, the last day of the summit, by picking up plastic litter and other waste. Modi tweeted: "Since yesterday, many of you have been asking – what is it that I was carrying in my hands when I went plogging at a beach in Mamallapuram. It is an acupressure roller that I often use. I have found it to be very helpful."
