It has evolved into one of New York’s longest-running fights over an estate.
For more than a decade, the family of C. C. Wang, a collector whose name graces a gallery at the Metropolitan Museum of Art, has been battling over a trove of classical Chinese paintings and scrolls that has been described as among the finest in the world.
