Based on the Chinese lunar-solar calendar, Tet Nguyen Day is a sacred holiday in Vietnam. It marks the beginning of spring and the Lunar New Year. In Charlotte, Vietnamese-Americans honor their home country with traditional and modern festivities that include foods such as báhn mì and pho, as well as cultural art, games, dances and more. And if you’re still fired up after a full day of celebrating, stick around for the concert beginning at 6:30 p.m.
