On the composition of glycolic acid
There are those who are good at studying the composition of glycolic acid in the world, aiming to study the composition of glycolic acid. It is thoughtful, walking among things, observing its characteristics, and analyzing its combinations.

In the genus of grass and trees, explore the contents of the leaves and observe the accumulation in the stems. When encountering strange grass, take its juice, and test it with exquisite methods to determine whether it contains the raw materials of glycolic acid. See different trees, study their skins, and hope to find the key ingredients.

And in gold and stone and the like, fine-tune minerals. Or dig three feet into the ground, get a ore, and bring it back to be refined and fractionated with tools, to check whether it has glycolic acid-related properties. Or visit the mountains and rivers, and observe the stones of the spring, and think that the water can dissolve its ingredients.

In animal matter, and spare no effort. Look at the feathers of birds and animal hair, observe the things they touch during their life, or examine their blood and fat in detail, hoping to obtain the elements of glycolic acid.

This person is on the road of exploration, not afraid of hardships. When facing problems, repeatedly investigate, gather the wisdom of everyone, and accept the words of hundreds of schools. Although the road ahead is long, his heart is firm, and he is determined to know the composition of glycolic acid to the fullest extent, so as to clarify the mystery, and use it for future generations, so that this study can be greatly expanded.
