Starting on July 18th, Lotte will be launching a new ad campaign for '2011 Chungha Soju', led by actress Yoo In Na. Under the slogan of 'creating a fun drinking culture', the advertisement will focus on promoting the clean taste of their 'Chungha Soju' brand for people who are against over-drinking and mixing drinks. To best model their innocent image, they've brought in Yoo In Na to clean up a drinking culture that's become filled with bad drinking habits.  Representatives explained, "We're a brand that has been working for 20 years to promote clean drinking. This year, we'll be renewing our brand with Yoo In Na to promote a fun drinking atmosphere." Starting this month, advertisements will be running both online and offline under the new marketing strategy. Source + Photo: News Time via Nate
