Mourning to the Earthquake The Chinese State Council declared a three-day period of national mourning for the earthquake victims starting from May 19, 2008. The Chinese National Flag and Regional Flags of Hong Kong SAR and Macao SAR were raised at half mast. At 14: 28 on Ｍay 19, 2008, a week after the earthquake, the Chinese public observed silence to express mourning; vehicles, vessels, trains, and air-defense alarms sounded, followed by a 3-minute silence.

In some insect nests special accommodation is provided for the young and for food storage. Many nests also have devices for regulating the temperature
