Bringing my dog for a check-up, I saw Dr. Sun again, and I was overjoyed. Two years ago, when all the doctors were at a loss and had no better treatment options, it was only Dr. Sun who suggested active treatment and immediate surgery. His persistence gave me great confidence and dispelled my thoughts of giving up. The surgery was successful, and my dog recovered well, now living a normal life. Without Dr. Sun's persistence and responsible attitude at that time, my dog might have already passed away. Here, I sincerely express my delayed gratitude to Dr. Sun after two years!
