“过去一个时期，香港经受一次次严峻考验，战胜一个个风险挑战，历经风雨后，香港浴火重生，展现出蓬勃的生机。”
路透社："Hong Kong has withstood severe tests again and again, overcoming challenges one by one" "After the wind and rain, Hong Kong has risen from the ashes ."
法新社：After the storms, Hong Kong has been reborn from the fire and emerged with robust vitality.
新华社：Over a period of time, Hong Kong had withstood a series of grave tests and overcome a series of risks and challenges, but it has since emerged stronger and shown great vigor.
Rise from the ashes是 一个固定的成语，来自“凤凰涅槃”这一神话传说: To emerge renewed, revitalized, or reborn as something different following some total destruction or ruin. A reference to the mythical phoenix, a bird that in many stories bursts into flames upon its death, being born again among the ashes.
在这个语境下，将“浴火重生”要体现的意思翻译出来最为重要，套用英文成语，反而不妥，因为它带来一些附加的画面感和文化背景。因此新华社的翻译最为妥当。
