I found this book apparently written by Lao Tzu. For what I search on the internet there are 2 translation to english: one made by Hua-Ching Ni and the other by Brian Walker.
I tried to find Hua-Ching Ni version but for the moment I found only a paper book – The Complete Works of Lao Tzu: Tao Teh Ching & Hua Hu Ching. Until I’ll buy one, I read Brian Walker’s version an try to translate it to rumanian.
More about Hua Hu Ching on wikipedia:
Brian Walker version can be found here:
For the next eighty-one days I’ll be reading, meditate and translate it to rumanian.
