After the proposal:
1, wash your hands before playing with gourds. Keep it clean and try not to wear cosmetics;
2. Don't play with the gourd too hard. Because there is a thin skin on the surface of the gourd, rubbing hard will hurt the skin, and even cause the skin to fall off and form patches. Affect the appearance. Rub hard, hanging porcelain will be slower;
3. Don't oil the gourd. The surface density of gourd is much more uniform, delicate and hard than that of walnut shell. The density distribution on the surface is also very uneven. The degree of oil penetration will not be the same. Causes uneven skin color on the surface of the gourd;
4. It is suggested to put a cloth plate or a cloth hand plate when playing. Avoid sweat seeping into the gourd, causing certain injuries. Because, sweaty hands, high moisture, high acidity. In human sweat, water accounts for a large part, generally containing 1~2%, and a small amount of urea, lactic acid and fatty acids. Too much acid and grease will make the gourd black.
