There are several kinds of agarwood, depending on what purpose you choose.
For home decoration, it is recommended to choose a well-known agarwood merchant in Shanghai, such as Tianhua agarwood, an old enterprise with a history of more than 50 years from Taiwan Province Province, but you can only join the club after being introduced by an acquaintance.
For personal entertainment, if you choose a small bracelet, you can get a basic understanding from some channels and know the basic maintenance and skills of agarwood, so that you can find some relatively formed agarwood enterprises like Xiangxiangtang in the deep water area of Shanghai.
To buy wood, it is suggested to go to some old antique market stores in Shanghai, but the price is generally inflated. It is suggested to ask some expert appraisers for help.
Try it casually. You can buy it in any antique shop in the market. It is generally white wood, which is also considered as Daphne, but it has no market value and collection value.
