Spring makes people feel high, and it is also easy to get angry and upset. Moreover, in spring, the eyes are more likely to be astringent, dry, swollen and unclear. It is also because of hyperactivity of the liver and rising internal heat, and the liver meridian is connected with the eye meridian, which directly affects the eyes.

As we all know, Cantonese people pay more attention to health preservation. For example, in terms of protecting the liver and improving eyesight in spring, Chaoshan people in Guangdong have a trick: peel pears into pieces, drop a drop of white vinegar on each pear and eat it directly, 1 day 10 piece. Whether adults or children, as long as there is nothing wrong with the stomach, you can use this folk prescription. This is because "sour sweetness turns into yin", sour taste enters the liver and nourishes the liver, and sour sweetness can nourish the liver and yin. In dry spring, this method of eating pears can improve the acidity and dryness of eyes and achieve the effect of improving eyesight.

In spring, some people often have leg cramps, some people often have diarrhea, some people often feel sleepy, and some people have recurrent gastric ulcers. Why? This condition is called "liver hyperactivity and spleen deficiency". When the liver qi is hyperactive and excessive qi and blood flow into the liver meridian, the spleen meridian will appear relatively weak. Spleen governs blood, is responsible for transporting and transforming blood and irrigating the whole body. Spleen deficiency will inevitably lead to deficiency of qi and blood and poor transport, thus causing the above symptoms.
