Healthy and smooth is an auspicious word, which can only be used in other places on festive occasions and cannot be used blindly to avoid unnecessary misunderstanding. Usually, cities like birthdays, weddings, banquets and early years can be used, especially for the elderly, such as the 70th birthday of the elderly. It can be said that I wish you good health and prosperous career, which sounds better than wishing you health and safety. This means that health and safety are in your heart. This is the best blessing.
