As is vividly depicted in the first cartoon, the tender flower blossoms inside the greenhouse in spite of the gusty wind, driving rain and terrifying lightning. Unfortunately, as soon as it is exposed to the thunderstorm, it soon fades and withers, with its delicate petals washed away. The fact that flowers growing in the greenhouse cannot withstand the test of the storm indicates that too much comfort spoils the child. As the only child excessively cared by the parents, young people are often associated with the flowers. The greenhouse epitomizes parents' doting care which shelter the children from the thunderstorm, in other words, the competitive world. The greenhouse flower is too weak to survive in the wild, where weeds always flourish. In the same way, once young people met with some setbacks, they will feel frustrated and thus lose heart inevitably, which may well lead to tragedy of some kind. Only when a person experiences all sorts of trials and sufferings can he or she survive the blows of storms or misfortunes, and eventually establish himself firmly in the society. As the old saying goes, "Adversity leads to prosperity." Let's get out of the "greenhouse" to see the fascinating world, to mix up with people and get prepared for the fierce competition ahead.
