In 1984, control of the company was passed to Wonowidjojo's son, Cai Daoheng/Tjoa To Hing (Rachman Halim), who subsequently became the richest man in Indonesia.

He started buying land and raw materials in Kediri and soon began producing his own klobot kretek, which he marketed under the brand name Inghwie.

Sarman, one of the original 50 employees who had followed him when he quit Cap 93, suggested he put a picture of the warehouse on every packet of his kretek for good luck.

Wonowidjojo considered this a good idea and asked Sarman to design the logo, commenting: "We should leave two doors open, two half-opened, and one closed.

In 1979, Wonowidjojo completely renovated Gudang Garam's production system, ordered thirty rolling machines, and developed a new formula for his machine-made kretek.
