According to the observation of China people, there are three kinds of phenology in summer solstice. Wait for the antlers to untie, the cicada to sing, and the Pinellia ternata to be born. From the summer solstice, Yin Qi was born, and the yang began to decline, and the antlers began to fall off. When the public knows the belly, they sing, and Pinellia ternata, which likes yin, begins to grow in the algae.
In the traditional concept, if the antlers don't fall off in summer solstice, it will lead to war, cicadas don't sing, people's hearts will deteriorate, Pinellia ternata won't grow, and people will get sick easily.
Health preservation in summer solstice can clear away heat and relieve summer heat and promote appetite. Ginger plays a particularly important role in healthy food from summer to Sunday, which means eating radish in winter and ginger in summer. As Confucius famously said, "Don't eat ginger, don't eat much". Ginger is a very good health food in summer, which can help yang and promote yang.
In addition to diet, nourishing the heart is also an important part of summer solstice health care. It's very hot in summer, and it's easy to get upset. At this time, you can vent your depressed emotions through meditation, so as to achieve the effect of "being calm and naturally cool".
Zhang Lei, a poet in the Song Dynasty, wrote in his Summer Solstice: "Raising children means that luck changes suddenly. The world is full of unknowns, and the gloom gives birth to nine plains. The life of killing people suddenly becomes more difficult, and it will grow up in cold and hot. Cui Wei is a dry cloud tree. It keeps its fragrance fresh. A few things are ignored, and gradual reason is inevitable. Look at the child, sit silently and forget to say. " The philosophical thinking of summer solstice is just like this poem. Only those who strive for self-improvement between heaven and earth can survive hardships and respect the laws of the four seasons, and their hearts can be truly free.
