Remember how others have helped you and learn to help others. There are always things in life, some people who always move us, and sometimes we don't know who they are, but their priceless love gives us eternal light. Some people do not have a high income, but they can support 8 lonely elderly people in 30 years; Some people, after receiving help from others, although they have difficulty walking, ask their father to take him on a tricycle to everyone who has helped him, and sincerely say thank you; Some people made a decision that touched the world when they learned that their illness could not be used, and they used the medical expenses donated to them to help more people, but they gladly faced death.

There are many people who are like this, they use their abilities to help others and warm the world like motes. Zen Buddhism says, "Those who love love to return, and those who are blessed are blessed."

When Cong Fei was hospitalized, didn't there be a lot of well-wishers to help Cong Fei?

Therefore, to help others is to help oneself, and to remember the help of others is to learn to help others. Life is a hard journey, held up with the big umbrella of love, filled with our common touch, and filled with our harmony and common laughter.

Love needs to be copied, love needs to be pasted. I believe that the grace of a drop of water can also be reciprocated by a spring. I believe that if everyone gives a piece of love, the world will become a better place.
