How many of Wild Agarwood?

Let me introduce some science to agarwood. Agarwood does not have annual rings, unlike other solid trees that have annual rings when cut from the trunk. For further study, agarwood does not have annual rings for reference. Unless the farmers who plant agarwood know when they started planting it. How many years has it been, then there are years to refer to.

If it is mined in wild deep forests, even the people who mine it don’t know how many years this agarwood has existed on this land? One can only say when it was discovered.

So I just say: #千亿 沉香, ten thousand years of Qinan

It is difficult to determine the fragrance formation time of wild agarwood. Generally speaking, the richer the balsam, the longer the fragrance formation time. It is not easy for the agarwood tree to continue to survive with a ''body with injuries''. Some giant lumps of agarwood are probably formed at the expense of the end of life. This is the difference between agarwood and ordinary spices, and therefore Resources considered non-renewable.

do you understand? Use your brain to think about the logic! How old is wild agarwood? Can't answer.
