For damp and hot fullness (stomach distension discomfort), vomiting and acid swallowing (swallowing the sour water in the stomach), coptis root is better than scutellaria root in clearing heat and drying dampness, especially in clearing damp and hot stagnation in the middle jiao. For cold and heat obstruction of the middle jiao, poor qi circulation, fullness and fullness of the lower heart (mainly refers to stomach distension and discomfort), nausea and vomiting, it is often used with scutellaria baicalica, dried ginger and pinnate.

What's there to say about filling light in photography?Filming was an important method to properly expose the details of the shadow. The following are some statements related to fill lighting in photography:
** 1. The purpose and effect of the supplementary light **
1. ** Prominent main body **
- In a complex scene, when the main body is not prominent, such as the picture has many elements and the character is the main body, if you want to shoot the big environment, the picture is easy to mess up. At this time, the fill light can make the character the brightest in the light and shadow of the picture, thus making the main body stand out.
- In a darker environment, the fill light could enhance the sense of layering between the character and the environment. Even if the character was blurred, it could also make it different from the background to avoid flattening the picture and enhance the sense of space and three-dimensional.
2. ** Make up for the lack of light **
- In a dimly lit environment, if there was no fill light, the character's face might turn black. This situation could be improved by filling light.
3. ** Creating an atmosphere **
- Different colors of light can create different ambiences. For example, using orange light to shoot in a cafe can create an atmosphere.
** 2. Light-filling equipment and features **
1. ** Reflecting Plate **
- The silver reflective board reflected strong light and reflected white light, which was suitable for strong shadows when the sun was strong. The gold reflective board also reflected high light, but it reflected warm light, which was suitable for shooting subjects that needed warm skin. The white reflective board was weak but gentle, which was good for showing skin details. The black reflective board was a light absorbing board, which could absorb some light when placed next to the face to create a three-dimensional feeling. The soft light screen could filter light when the light was hard, making the light softer and making the skin look more delicate. The multi-functional reflective board was a better choice. The common size was 80 centimeters (about 30 centimeters in diameter after folding), and it was more widely used.
2. ** Lighting Equipment **
- ** Continuous Light Source (Continuous Light Source)**: Its advantage is that what you see is what you get. It is more intuitive and is very friendly when you need to use the imaging lens to produce various light effects.
- ** Non-continuous light source (flash)**: It is recommended for portrait photography. It has good light quality.
- ** Mixed Light (Continuous Light + Flash)**: Able to utilize the advantages of both.
- Different lighting accessories such as standard covers, soft light boxes, radar covers, reflective umbrellas, etc. can be selected according to the desired effect.
- There were also flashlights for portrait photography. The beam size could be adjusted, and there were many colors (such as white, yellow, orange, and red) to choose from. The battery did not need to be replaced, and it could be used to create different environments.
3. ** Early Flash **
- The earliest flash lamps could be traced back to Germany in 1887. They used a mixture of powder of lithium, potassium pernate, and sulfur as luminous materials. When the lithium was energized, it reacted with oxygen to produce strong light (and at the same time produce a large amount of smoke). Later, it was developed into a flash bulb (1920s). The aluminum and magnesium-wound wire was placed in an oxygen bulb for one-time use. The bulb needed to be replaced. Nowadays, electronic flashes were mostly used, which were composed of a lamp tube, a transformer, and a control circuit. They used the principle of high-voltage discharge to emit light (the noble gas in the lamp tube was illuminated by the high-voltage electric field formed by the discharge of the transformer). With the development of LED technology, some mobile phones that could take pictures used LED light instead of traditional neon tube flashes.
** 3. Use of supplementary light **
1. ** Light from different directions **
- In portrait photography, lighting from different angles would produce different effects. For example, filling in the light from different directions could create different light and shadow effects.
2. ** Control brightness contrast **
- The fill light helped to control the bright contrast in the picture, making the picture look more ideal.
