Wechat, which is thankless, talks about how to express the mood at this time.

We all stumble and grow up in time, and then leave the original appearance little by little. At one time, we didn't have any distractions at all, but after time polishing, we all learned to pretend, learn to face life with a mask, and learn to face the world in another way. We are no longer innocent and carefree, and we are not the same, but we still have to learn to be strong, brave and smile. Learn to hide your worries so that others can't easily see through us. We learn to disguise, learn to be strong, learn to smile, but forget what we really are.
