With years of legal background and experiences, the partners of CTW are among the pioneers of the legal profession in China. Before becoming attorneys, most of the partners worked with Chinese government institutions, judicial organizations, or famous domestic enterprises. Their in-depth knowledge of the working mechanisms of these organizations and their social connections are of invaluable support to our legal services.

The primary goal of CTW is to achieve the best interests of our clients. We comply with professional practice standards and are 100% responsible for matters delegated to us.

Guided by this principle, our attorneys approach cases from the clients' perspective in order to better understand their needs and deliver feasible, creative, and cost-effective solutions.

CTW has strict quality supervision and risk control systems, including risk prevention and control, teamwork and accountability, and computerized processing procedures. At CTW, we determine whether conflict of interest exists before we accept any new project. For each complicated case, we set up a project-based team of partners, attorneys, and paralegals with a strict quality control and accountability system.
