High on the list of hot topics at every summer and winter Olympics are legacy and sustainability. Those themes also featured prominently in this year's PyeongChang Games, as the organizers set out to stage an event that will impact the host country for much longer than the 17 days of competition.

"We felt the education program is a big legacy," said Kim Aram, legacy senior project manager of the PyeongChang Organizing Committee for the 2018 Olympic & Paralympic Winter Games (POCOG). "Most South Koreans in high schools study 17 to 18 hours every day, and it is unhealthy. Our program was designed to teach about how to eat healthy, how to stay healthy, and also a little bit academics on working in sports industry," he added.

The host nation grabbed two medals in skeleton and bobsleighs at the Games. Kim said the victory is like an immediate legacy, with more and more athletes from different countries would like to come to PyeongChang and train here.

Meanwhile, Kim thinks that South Korea has previously focused mainly on skating events during cold months, but now people’s mind has been changed as now they've known more kinds of winter sports other than skating.
