1. The lyrics of the opening song "Mission" of the TV series "No Regrets" are as follows:

A belief is engraved in my heart

How many years have passed in the blink of an eye

Silent vows to stop time

Suffering silently and alone

A lifelong motto to bless ambition

No regrets and all the heart remains< /p>

Don’t forget your original intention and keep your promise

Fearless hardships

Gather the strength of a promise without regrets

A firm vision and determination Far away

A face with a friendly smile that is fearless of hardships

Uprightness ignites the light of hope

Burning a lifetime of candlelight and moving love

Worthless and still in my heart

Facing the stormy waves without flinching

Not afraid of the twists and turns of fate

Gathering strength with a promise and no regrets

Firm eyes and determination In the distance

A friendly and smiling face fearless of hardships

Upright and igniting the light of hope

Dedicate your life to immortal faith

Everything on your shoulders Deep love and great righteousness

Perseverance in pursuit without regrets

Righteousness and glorious glory
