According to what you said, basically all cards are suitable. Credit cards are used regardless of regions, and it is also very convenient to use when going out, such as buying air tickets and swiping room charges.

since you don't go out much, choose your favorite card screen. If you often eat out, you can get a Peony Gourmet Card (special restaurants offer discounts), if you have a private car, you can get a Peony Zhongyou Credit Card, and PetroChina gas station offers a 1% discount for refueling. If you often shop, you can get a Peony Gome Card, Peony Parkson Card, Chow Tai Fook Peony Credit Card, etc. They all have cooperative relations with ICBC, and they have discounts or many points.
