On February 16, 2003, the two-color ball of China Welfare Lottery was officially released nationwide, which was the only computer lottery game jointly sold in China at that time. In the past six years, Fucai two-color ball has successively completed a series of work such as marketing promotion, regulation adjustment, team development and credit construction, and launched a series of marketing measures such as "dumping Sanqi", "holidays", "giving away 1 100 million yuan" and "rewarding 1 100 million yuan", and launched a large-scale "approaching two-color ball" campaign to jointly sell provinces. Especially since 2004, marked by the lottery with two-color ball TV live broadcast, the credit system of two-color ball has been gradually improved, the credibility has been continuously enhanced, and the brand reputation has been continuously improved, which has created a brand-new situation of "openness, fairness and justice" and has had a far-reaching impact on the development of welfare lottery in China.
