Old wood is valued in China for its aged patina, its markings and a beauty that lives on long after the tree was felled. Zhao Xu talks to a scholar who has made it his calling to study and treasure wood.

Mi Hongbin raised his very first question about wood at the age of 7 as he watched a traditional Chinese doctor take his patient's pulse.

"What he did, basically, was to place his fingers gently on the patient's wrist and count the throbs," says Mi, an independent scholar with a special bent for the mystical and philosophical aspects of Chinese culture, and a soft spot for wood.

But it was the prop, not the healing that held the young man's attention.

"What intrigued me was not that he could come to a diagnosis through such a simple but mystified procedure, but the fact that it couldn't be performed without that small chunk of wood, on which the patient rested his wrist."

That "chunk of wood" has been part of the healing paraphernalia for ages, and is known as a "pulse pillow". Many have been used for decades, and all have been polished by constant use to a shiny patina, oiled by numerous encounters with human skin.

"To a child like me, it was a symbol, an essential part of a ritual," Mi recalls. "And I asked my father: 'Why wood? Maybe we could use something else, like a cotton-stuffed real pillow?'"

His answer was brief, but it took Mi the rest of his life to decipher the words.
