Brand got introduced in May 2001 by TAIWAN TOBACCO & WINE BOARD

A very rare brand, sold at Taiwanese Duty Free only. The filter has at the top a hole with the shape of a heart and the bottom of the hole is red. So if you look at the filter you see a red heart inside.
The story behind it:
If you pronounce 5-2-0 in Chinese language with Taiwanese dialect it sounds almost the same as the words 'I love you'. In the 1990's where teenagers used a lot pager's to exchange numeric codes by using a code book to translate them, there 520 was as well used to express 'I love you'. When the brand got introduced to Taiwanese market in May 2001 various organizations protested against the conjunction between cigarettes and love. Because of the heavy objections the producers took off the brand from local market and sell them now at their Duty Free shop only - at Taiwan itself the brand got renamed to YES.
