Multidisciplinary professional services networks were an important phenomenon in the late 1990s and early part of 2000.

Multidisciplinary professional services networks are organizations formed by law, accounting and other professional services firms to offer clients new multidisciplinary approaches solving increasingly complex issues.

WSG, also branded as World Services Group, is a multidisciplinary professional services network of independent law, accounting and investment banking firms.

In 2009, Dacheng joined World Services Group, an international multidisciplinary professional services network of independent accounting, investment banking and law firms, becoming the first China-based member.
