BIM technology can add time dimension to three-dimensional space model to carry out 4D simulation construction, which is conducive to the optimization of construction period. Based on BIM technology, 4D simulation construction can put forward a virtual construction scheme, which can pre-process various possible induced situations in the construction. The application of BIM technology in the construction stage can reduce possible errors in the process of information transmission and reduce rework.Soil-brown: water caltrop*, jiuxiong (lagerstroemia subcostata), chestnut, waxberry (myrica rubra) …Event Pearl:World-renowned chef Gordon Ramsay judges families from across the country as they compete live in a high-stakes cook off.ReportCharming Vietnam 20171108 Episode 2　　清末，古都北京有个叫桂山破落大户以房产抵押得到一只羽毛全白的白家雀，并由此引发出一连串曲折动人的故事。大妞、二妞姐妹因“白家雀之死”被骗进王爷府，结果大妞被王爷奸污后含恨而死；二妞不畏强暴，奋力反抗。最后在朋友们的帮助下，她逃出王爷府，奔向心目中向往的没有罪恶、充满善良自由的地方。
