Zhao Wensheng wants to wear it every day since his wife can't wear it, he will have his wife wear it. Since it's meant to be worn daily, Jiang Mei's wedding ring on her ring finger, regardless of the design or material, was chosen for its simplicity, durability, and elegance. It's not noticeable to the average person, but as long as the couple themselves can see it, that's enough.
Initially, Young Master Jiang chose a pure silver ring simply because his wife liked it and she wanted simplicity. He himself is a military man working in the army, and it's not suitable for him to wear a wedding ring every day. Moreover, if the silver ring is exposed to the air too much and gets sweaty, it can turn black and requires frequent care. Manman often stays at home and likewise doesn't wear it because it's precious. Besides, she is a chef, a housewife with many household chores to do, swinging around can easily damage the more fragile silver ring.
