Mandarin (普通话) is the common language in China, but each region has its own dialect (方言). For travelers, a familiar accent can refresh the memory of their hometown.
According to an official video by the Chinese Education Ministry’s Language Com mission, among the more than 130 languages spoken in China, 68 of them are spoken by less than 10,000 people; and 25 by under 1,000.
Hu Shuning, a dialect preservationist, said, “I think it is natural with a society’s development that a dominant language appears, but from a cultural aspect I think dialects are still important, because they reflect cultural diversity.”
“Mandarin can take you further, but your dialect tells you where you come from,” said Wang Han, a well-known TV host.

The cicada（蝉）has an interesting life cycle, but most of us only become aware of these insects in summer when they reach adulthood and begin their calls. 1.Some, like the Golden Emperor, have complicated songs.
