[1] Besides being one of the hardest of the poems to translate, we have here #10 specific mention of  氣, Qì: this word has been diversely translated into English as energy, force, spirit, breath, etc. However, these translations are inadequate as they reduce the notion to one aspect or profile. Even the Chinese do not have a standard definition of the term, even in qì gōng.
