Under the Dome, a documentary on air pollution, has provoked national discussion about tackling smog.

"Last night I watched the documentary produced by Chai Jing, a well-known Chinese journalist, host, author and environmental activist. Then this morning I sent a message to her to express my gratitude, for she had aroused the public's concerns about the environment from a special perspective - the public health, which deserves our admiration."

"The government and other national departments have to stand up and formulate measures, sometimes they even have to put some brakes on the economic development to make a change, which is the hardest part of curbing the haze pollution."

"Just like forest police, the environmental protection department should be endowed with the power of enforcement and investigation. That is what we should do to expand their authority. The establishment of environmental police by equipping them with the 'gun' is vital."

"At present, China's environmental governance is inefficient. The main reason is not that environmental protection department lacks tooth, but the tooth is not hard enough. The monopoly of the central enterprises cannot be gnawed at easily. We suggest that the State should seriously study find out the source of pollution, disclose the charges for the public environmental protection, and improve the efficiency of environmental governance."

"Whenever I stare at the night sky, thinking how our lonely earth rotates, I feel a sense of indescribable attachment and affability. Someday I will no longer exist in this world. But as long as my child is here, this world has every connection with me. So I stare at it, just as I stare at you. I protect it, just as I protect you."

"Breaking monopoly sounds exciting, but it may incur more smog."

"What Chai Jing's nationality is or whether she understands pollution or not is not important. We don't need to care about the use of technology in the documentary and shouldn't focus on whether she puts forward solution or not. The outcome of the documentary is that it made the entire society pay attention to the haze, it set off discussion and drew national attention. The film achieved its mission. Have we ever attached great importance to haze like we have now? Never."
