National Day of the People's Republic of China
Every year, many large groups of flowers are put along Beijing's Chang'an Avenue. The 2017 centerpiece measured  across its base and stood  high. Lan Hailang and dozens of other designers and officials made it from April to September, with at least 70 big design changes. The finished designs should show how China is getting better and what it plans to do next. Parts of the 2017 flower designs show the Belt-and-Road Initiative to make China's connections with Central Asia better; other parts show ways Beijing and Tianjin are going to be better over the next few years.
