Answer: Camellias are hardy and need flower protection only when the temperatures drop below freezing. Even then only the opening buds showing color are likely to be damaged. After the cold, the tight buds should continue growth and flower. Plantings are either early, mid-or late-season bloomers.
Beijing Population 2017. The current population of Beijing according to the 2010 census, as reported by the official Chinese Government statistics agency, was 19,612,368. The population at the beginning of 2016, according to some estimates, is 21.7 million.
The study also found that Beijingâs population density soared by more than 60 percent from 1999 to 2011 to 1,300 people per square km, a level described as unsustainable. The dense population weighs heavily on the cityâs roads and public transport systems, the report said.
