The answer is simple: 正直- being righteous. They all know this word 正. It means upright straight, correct, right, and justice.
Over thousands of years, generation by generation, Chinese are acting on this world 正 which carries huge wisdom through 4 hiding simple Chinese words in it:
下 - Low; down; withdraw; retreat. When #COVID19 first attacked them, they all stayed low at home, retreat from works to contain the virus, together. Naturally, they take it as everyone’s responsibility.
止 - Pause; hold back; disciplined; restricted; boundaries. When they knew they must hold back, they stay home strictly. They are all highly disciplined in quarantine, together.
工：Work; trade; serve; skill; profession. When the pandemic attacked them, they all worked hard in contributing their energy, skills, professional supports, and their pure hearts with big #love. They built Mobile Cabin Hospital in WuHan within 6 days, under the greatest pressure from all over the globe. But, they succeeded together.
上：Up; start; advance; develop. Now, they are all freely enjoying their #life, advancing up and developing forward.
And, they want and they are ABLE to help the world to be better now. They are #open and amazing!
