What is the meaning of unification? The Tao Te Ching says: "The Tao gives birth to one, two gives birth to two, two gives birth to three, and three gives birth to all things". Nowadays, society is full of pressure, the pursuit of material enjoyment, often forget the spiritual cultivation, lost themselves. The road of life is far away, one step forward and three steps back, looking back at one's beginnings. Here, there is no difference between Eastern and Western borders, no difference between ancient and modern painting techniques, we absorb all the techniques and express our own works, which is the so-called "All is One".
