Hi Dad, welcome back to Taiwan. I know you from the video. I feel that you are a very wise, caring, and humorous person. God has given you a test, but He can't beat you. May you be safe and healthy.
As someone whose elderly Asian parents could not make the long distance flight to the US for my wedding, it moves me to witness your dad being willing to endure the challenges of flying to Taiwan to help out his church and see his beautiful daughter. Happy that you guys took such good care of him and that he got to savor his favorite foods.
Your dad took such a long flight with his physical limitation, for the sake of supporting local church at TW while reuniting with family, is so touching. Good bless you and family.
