The Qingming Festival is coming, and it's time to pay respects to our ancestors. According to old customs, people burn paper money, add new soil to the graves, and insert a few new branches on the graves... But now, the convenient, fast, and green online worship has begun to be promoted. Recently, I browsed more than a dozen memorial websites and found that some people have already started to commemorate their ancestors and revolutionary martyrs online. One of these websites, the Premier Zhou Memorial Hall, has received 4493 visits.
