Where in China do sandstorms usually happen? What is the first sign?S4: In the west and northwest China.S5: But it also happens in Beijing often.S6: Before the sandstorm, there is usually a heavy wind and dry weather.S7: The sky is yellow.S8: One afternoon of last spring, when I was at school, the sky was yellow.
