    A grand international horticultural（园艺）exhibition kicked off on April 29, 2019 Monday in Beijing. Chinese President Xi expressed his hope that the green development concept（理念）embodied（体现）by the Expo park would be spread to “every corner of the world”.

The International Horticultural Exhibition 2019 Beijing is the highest-level and largest international fair held in China after the International Horticultural Exhibition held in the southwest city of Kunming in 1999, the 2010 Shanghai World Expo and the first China International Import Expo in 2018.

“The development model of ‘killing the hens for eggs' and ‘draining（排空）the lake for fish' is at a dead end, "Xi said in his speech at the opening ceremony of the Expo. "The future will be illuminated（发光的）by eco-friendly development that is in accordance with the rules of nature.”

“China's ecological civilization（生态文明）development is on fast track. People will live in a better environment with blue sky, green mountains and clear water, "Xi said." We should protect the ecological environment like protecting our eyes and value it in the same way we value our lives.”

“Only with concerted efforts can we effectively（有效）deal with global environment issues such as climate change, marine（海洋）pollution and biological protection and achieve the United Nations 2030 Agenda for Sustainable（可持续的）Development goals," he said.

He put forward a five-point suggestion: pursuing（追求）harmony between human and nature, prosperity（繁荣）based on green development, a passion for mature-caring lifestyles, a scientific spirit in ecological governance and joint efforts to deal with environmental challenges.

"The Beijing Horticultural Expo, themed ‘Live Green, Live Better', is one of the major international events hosted by China in 2019, which marks the 70th anniversary of the founding of the People's Republic of China. It indicates（标识）that China has changed from a participant（参与者）in global green development to a contributor and leader, "said Wu Shunze, an expert with the Ministry of Ecology and Environment. A total of 110 countries and international organizations will attend the 162-day event.
