Customers from Colombia came to see organic fertilizer machines

On 9th May,2017  The Colombia came to visit our factory. They wanted to buy a organic fertilizer production line. Few months ago, they sent us some materials to test our machines. We tested it and the result was good. So they decided to come to our factory.
First , they checked our machines in our factory. We introduced them in detail. Then we lead them to a organic fertilizer factory in another city. We showed them machines and how  the machines to produce fertilizer in this trip.
