honestly, from the earlier I can not sleep because people play fireworks here and there ... instead of hate, but in LN if there is a fireworks display is usually performed in the field or the beach ... the people here (jakarta, t4 others I do not know) of young people go around playing the fireworks ... honestly, I was scared and finally TAXABLE FIRE POWER CORD or disability My question: 1. what the government or the mosque does not forbid it? 2. why go with fireworks? 3. what does it mean widths = new Islamic year?
