If you are a beginner in fragrant incense, it is recommended to watch Lingtai Aquilaria sinensis and Xiangxue Huidian, which is quite good for getting started with fragrant incense. Then, after having a certain foundation of incense, I began to read Xiangpu and Xiangcheng.
In fact, the PDF books in these ancient libraries have both modern and ancient incense, as well as the introduction and depth of incense.
If divided by time, there are differences between modern incense and ancient incense. For modern incense, you can look at Xiangcheng, Baichuan Xue Hai, XiangXue Xue Store and Xiangpu, and the traditional incense in China, and you can look at the ancient Chenxiangpu and Xiangcheng. Experience the compatibility and concept of ancient incense prescriptions.
