All my love to your family and to you Weihan. I am incredibly saddened to write these words. Your smile and positive energy was always contagious. Your thoughts were always deep and insightful. Your friendship was always a treasure. I will never forget our ski trips together, our competition to eat the last bite in the table, and our beers at the George. You are an amazing father, son, husband, and friend. I wish your family strength in these sad times. Even though you are not physically with us, you have lived a life full of purpose and you have given us many special moments to remember you for. Rest in peace my friend.
