Why do American bears hug each other tightly?

According to the British "Daily Mail" reported on March 27th, American photographer Shayne McGuire took a group of very touching photos around Lake Clark, Alaska: a pair of brother and sister who were separated in the jungle hugged each other tightly, and generate showed a spark of love.

It is reported that the reason why the mother bear drives her cubs out of the nest is to make them independent as soon as possible. Although the experience of self-reliance is doomed to be difficult, it is a necessary stage for them to grow up. Close brother and sister were exiled to the jungle by mother bear. When Brother Bear recognized Sister Bear, he grabbed Sister Bear and held her tightly in his arms.

Sean said: "I didn't realize what was special about this set of photos at first." When I looked at them later, from their facial expressions and body movements, I found that they were full of love for each other. "
