Co-all

共同所有是一种社会Q＆A，以帮助人们用正确的专家联系。

Co-all is a new concept of social media (social Q&A) that filter and classify people by their expertise and profession to get the question from questioner (consumer) and answer them by their knowledge and finally provide some suggestion for their questions for free.

In this method we place a professional gateway between the Consumer and the Provider. This strategy allows Consumers to send their desires as questions through this gateway and receive the best answer from the Professional community.
