After the lottery was drawn, he was told that the bet failed and a refund had been made. This was the painful experience of Mr. Li, a Guangzhou citizen, recently. In recent years, websites and mobile phone clients for lottery betting have sprung up, attracting many citizens to buy them. However, is it reliable to buy lottery tickets online? Can you really get money if you win the jackpot? In this regard, the person in charge of the Guangdong Provincial Welfare Lottery Center was interviewed by reporters. It said that no unit has yet been approved to carry out the Internet sales business of welfare lottery tickets. Currently, all online sales of welfare lottery tickets are illegal. Lottery players must not participate in betting to avoid property losses. <br> </div><br> </body><br> </html><br> </p> </div><div class="nphpQianMsg"><div class="clear"></div></div><div class="nphpQianSheng"><span>Statement：</span><div>The content of this article is voluntarily contributed by netizens, and the copyright belongs to the original author.
