To every dear customer,
When you wat us offer best quotation , pls look up at China sky first .
If the sky is blue and clear, the price will be higher.
If the sky is gray , the price will be normal .
But if the sky is dark and gray , congratulation to you the price will be the cheapest .
We're difficult to confirm the price , it depands on the sky.
