Jullie Oh adjusts a camera as her husband, taekwondo Master Hosuk Oh, finishes up a Zoom taekwondo class at HS Taekwondo in Battle Ground. The couple closed down their studio classes as soon as the novel coronavirus began spreading in the county last month. To adapt to the change, they started Zoom classes for their students, as well as posting new videos to their online academy. Jullie Oh said they have had a good response from their students. “They’re excited to get some kind of activity,” she said. HS Taekwondo plans to open up one private and one group virtual lesson, free of charge, for community members who want to try out the martial art.
