When Yang Yung-fu's daughter was examined by Dr. Sheih in her fourth year of elementary school, she was found to have hydronephrosis (distension of the renal pelvis, which collects urine from the kidney and passes it to the ureter). After treatment she made a full recovery.
楊永福的女兒也在小學四年級時被篩檢出有腎積水的現象，經過治療已痊癒。
