What are some old customs and ideas that you can't tolerate?

For me, the most intolerable thing is to burn paper money during rituals! Sacrifice for us, this is more than custom, but also a kind of memorial to the ancestors and spiritual support. However, with the development and progress of society, sacrifices do not mean that you have to burn paper money, but you can choose a more civilized and environmentally friendly way, such as Internet sacrifices, flower sacrifices and so on. Now has been ordered to ban the burning of paper, but this trend is still difficult to eradicate, there are still many people do not understand. Burning paper not only can not be environmentally friendly, more likely to cause fire, this will cause pollution habits are harmful. In the revered low-carbon environmental protection today, reduce carbon dioxide has been linked to the moral, and can we do low-carbon life, to put an end to the burning of paper this goal is also directly related to our environment and health.
