Do you see the fern (蕨类植物) and the bamboo? When I planted their seeds, I took good care of them. The fern quickly grew from the earth. 3 nothing came from the bamboo seed. During the following three years, the fern grew more plentiful. And 4 nothing came from the bamboo seed. But I did not quit on the bamboo. Then in the fifth year a 5 sprout (新芽) emerged (出现) from the earth. Compared to the fern it was 6 small and insignificant. But just 6 months later the bamboo 7 to over 100 feet tall.
