By the way, it is basically impossible to give it to you without spending a penny. It takes time and energy to keep a dog, which means giving someone a red envelope. Generally, red envelopes range from 200 to 600. These are equivalent to the usual fee for dog owners to feed and vaccinate their dogs. In fact, they are all about the same or more expensive. The puppy I just got only cost me more than two thousand yuan two or three months ago.
However, very few people really don't want you for a penny.
