What's the biggest worry for horticultural expo? Cold fronts

Cold fronts that can push temperatures down abruptly will be the main weather threat during the International Horticultural Exhibition 2019 in Beijing's Yanqing district, the city's meteorological service center said recently.

Han Chao, deputy director of the center's disaster reduction office, said that other weather risks during the expo - which will last 162 days from April to October - include snow, strong winds and fine dust.

Zhou Jianping, deputy head of the coordination bureau of the expo, told the China Meteorological Administration that its work will be taken seriously.
