After discussing this idea with the ObiSofts senior management back in the United States, Herfken and his team agreed. As a result, many calls and emails were exchanged in the months following to discuss details, opportunities, and possibilities. Ling wanted to work for ObiSoft, and could see the company's potential in China. As a result, Ling invited Herfken and his wife to visit him in Shanghai. After three days together of sightseeing, yum cha2, dinner, and discussion, their relationship was established. Two months later, Ling and ObiSoft signed a partnership agreement. Herfken was cautiously optimistic and impressed with Lings motivation, his English-language capability, and his knowledge of the software industry both internationally and in China.
