This crane project we quoted is in December, 2017, but during following two months, I follow up this project progress, customer replied they are still waiting for their client's feedback, then I send some package and delivery pictures to this customer then, and also send our company profile for our client's reference. In March, customer let us update CIF offer to them, since our offer valid is only for one month, and also because of exchange rate, so we update a new offer with sea freight for them, and also send some quick-wear parts for free to them. Our customer very satisfied with our offer, then we signed the contract on this project.
