Ding-Jing Hall is the largest building in the Lin Family Mansion and Garden. It used to be the venue where the family hosted their guests, celebrated, and held parties or relative activities. The setting of Ding-Jing Hall is in the style of “si-he-yuan,” an architecture with four buildings situated around a central courtyard. The front yard of the hall is spacious. On the central axis of the building stand multiple doors and a corridor, leading the guests to the main hall.

In addition to offering a place for social life, ceremonies, and gatherings, the hall also functions as a venue to display antiques and old paintings. Of them, the plague "Ding-Jing Hall" was written by the owner of the garden, Wei-Yuen Lin. On top of that, the pattern brick walls in the frontage and the brick carvings on the two sides are also must-see.
