"Give someone a rose, there is fragrance in your hand" is an English proverb. It means a very common and trivial thing, even if it is a small thing like giving a rose, its warmth will gradually rise in the hearts of the sender and the receiver. Tell everyone that if you give, you will be happy. If you only know the harvest, you will lose happiness. This is often the case in life, which will bring convenience to others and bring convenience to yourself.
Our predecessors planted trees, while our descendants enjoyed the cool.
It takes several generations for trees planted by predecessors to grow into shade, and later generations can enjoy the cool, so it takes a long time for trees to grow. It also means that the current work may take a long time to reflect the benefits and values.
At the same time, it also shows the long-term and arduous nature of ecological environment protection. Only by protecting the environment from now on can we leave a living place for our future generations. We can't develop the economy at the expense of the environment. Sustainable development is the last word.
