Men's agate bracelets, sunshine jars, personalized military cards, etc. are all OK. Give him chocolates, hand-paint your blessings on him, and add a greeting card to write your comfort to him. Eating chocolates with deep affection, your uncle will definitely cheer up again.
Give him a suit. If your financial ability is limited, you can give him a tie. Wearing the tie you bought, your uncle will definitely be in high spirits. Don't worry too much, it will always get better. You can chat with him more to relieve his depressed mood. Knowing your good intentions, I think your uncle will not have the heart to let you down.
For work reasons, it may be because of work pressure. You can go out for a walk with him more often. Don't always think about work. Short-distance travel is also OK. If you are still worried about his physical condition, you can give him a necklace and bracelet with health care functions, so that you can feel more at ease.
