The term 'heavy competition' can be summarized by the four-letter word 'SUMO'. SUMO is a Japanese form of wrestling that has been practiced since ancient times. It is a highly competitive sport, with two wrestlers competing against each other in a circular ring. The goal is to force the opponent out of the ring or to make them touch the ground with any part of their body other than the soles of their feet. The winner is determined by the best of three rounds. Heavy competition is an apt description for this traditional sport.
