technical field

The invention belongs to the field of material processing, and in particular relates to a processing method for making imitation cypress materials from Chinese fir.

Background technique

Along with the raising of people's living standard, foot health care has become the new focus of current health care. Traditional Chinese medicine believes that there are more than 60 acupuncture points on the feet, accounting for 10% of the total number of acupuncture points in the whole body, all of which are related to the organs of the whole body. From the itching sensitivity of the soles of the feet, it can be explained that the sensitivity of its acupoints and nervous system is higher than that of other parts. Washing feet with hot water every night before going to bed can promote the smooth flow of Qi and blood, nourish vitality and delay aging.

Traditional foot baths are mostly made of cypress wood, which contains resin and has the characteristics of hard wood, high hardness, high density, excellent material, fine structure, and corrosion resistance. Untreated cypress wood can be soaked in water for 10 years without decay. Cypress wood is loved by the public because of its natural, environmental protection and healthy characteristics.

Cypress grows slowly in the natural environment, and the diameter of 30-year-old cypress is about 10 cm. There is a folk saying that "a thousand-year-old cypress is a thousand-year-old cypress".
