This is a public service announcement for the Heart to Heart Charity. We are a non-profit organisation that helps people in need. As theTet holiday approaches, we are asking you to think of those in our community who need help. Even today, we have unbelievable problems in our community. Many children and adults are hungry, cold and sick every day. Our goal here at Heart to Heart Charity is to help those people. To do this, we need your help. To help, you can do one of three easy things. First, you can donate food and clothes to our organisation. Your food and clothing will go straight to someone who needs it. Second, you can donate money to our organisation. We will only use your money to buy food, clothes, and medicine for the needy. Or last, you can donate your time and work in the office. We always need new volunteers. Your donation of any kind will always be welcome. So please contact us at 15 Ha Thanh Street. We are open from 8.30 a.m. to 10p.m. every day.
