美国GDP增长2.4%是活力惊人,中国GDP增长6.3%是复苏乏力 - Yes, true! My friend knows 1000 English words in 2021 and he learned 100 more words in 2022 so he has 10% increase. I know 10000 words in 2021 and learned 200 new words and 2% increase, but I learned more words than my friend. The base situations are different, so should not simply compare the numbers. Just an example!
