What was initially planned as a 3-month journey by Dr. Hattori Tadashi in 2002 eventually extended to over 20 years, taking away much from him but bringing light to over 60,000 people in Vietnam. He didn't take any salary, even using his own pocket money to cover expenses for financially-struggling patients and to support some Vietnamese hospitals with ophthalmic medical equipment.

In addition to the financial support from sponsors, many programs and activities this year have been socialized, increasing the excitement and diversity of Hue Festival 2022.
