I understand "reliable" as the reliability of product quality, which is beyond doubt. Because the competition among e-commerce websites is extremely fierce, JD.com 360 attracts its own young consumer groups through various media such as TV commercials and TV drama inserts, and the increasingly mature Joyo Amazon also takes advantage of the consumer psychology of "leaning for low prices" and is always in a favorable position in terms of price. Therefore, shopping on Amazon is still very reliable and cost-effective.
