The translation of public signs reflects the civilization and the culture level of a city, so it becomes more and more important. Meanwhile, environmental problems, energy problems, ecological balance problems, etc. become a common concern with the global environmental deterioration. Creating a good natural and friendly cultural environment will become one of the focuses of the whole world.

On April 1st, 2017, the Central Committee of the Communist Party of China and the State Council decided to set up a Hebei new security zone, Xiong’an New Area  . It is another new district with national significance after Shenzhen Special Economic Zone and Shanghai Pudong New Area. It is a historic strategic choice for carrying out the Millennium Program and state affairs. There are seven important tasks in Xiong’an construction and planning. The first two tasks are related to Environmental protection industry. Xiong’an New Area strives to become a green city.
In “Opinions on expanding opening to the outside world and actively use foreign capital adopted by the State Council”  , it is clearly stated that implementation of foreign investment policy to build an open area of New Development Zone is very important. With the establishment and development of Xiong’an New Area, it will attract more and more foreign visitors and industries from every corner of the world coming into China. With the increasing number of the foreigners, the environmental English public signs will become more important, because they offer foreigners more information on where and how to do to be friendly with the local environment in English which foreigners can understand easily.

The green development concept should be integrated into the planning, compilation, approval, implementation, supervision and assessment of the integrated development plan  . The most important thing is to form a joint effort to promote the construction of ecological civilization, and all kinds of behavior subjects, especially the government’s public decision-making, should be green.
