The reaction to this trailer is mostly positive so it will do well regardless. I love this fabulous Chinese cast and I don’t think they’ll let Hollywood mess with their culture.
Mulan doesn’t cut her hair unlike the animation and I like that.

Hi @marcusnyc20 bong-soo.
It’s so good to see you here. I am well, thank you <3. I hope you are doing doing well too.

I only read the translated version of the Ballard of Mulan.

Ballad of Mulan (6th century)
by Unknown, translated from Chinese by Wikisource

The "Ballad of Mulan" is a folksong from Northern Dynasties China. It recounts the story of Mulan, a girl who goes to war in place of her father. The pseudo-historical personage of Mulan probably lived in the fifth century, when the Toba, who dominated north China, were engaged in a long war with the Rouran on their northern frontier. It is thought the ballad was collected into an anthology of yuefu in the mid-sixth century, and later popularised during the Tang dynasty.
Translated by Jack Yuan (2006).

The sound of one sigh after another,
As Mulan weaves at the doorway.
No sound of the loom and shuttle,
Only that of the girl lamenting.
Ask her of whom she thinks,
Ask her for whom she longs.
"There is no one I think of,
There is no one I long for.
Last night I saw the army notice,
The Khan is calling a great draft –
A dozen volumes of battle rolls,
Each one with my father's name.
My father has no grown-up son,
And I have no elder brother.
I'm willing to buy a horse and saddle,
To go to battle in my father's place."

She buys a fine steed at the east market;
A saddle and blanket at the west market;
A bridle at the south market;
And a long whip at the north market.
She takes leave of her parents at dawn,
To camp beside the Yellow River at dusk.
No sound of her parents hailing their girl,
Just the rumbling waters of the Yellow River.
She leaves the Yellow River at dawn,
To reach the Black Mountains by dusk.
No sound of her parents hailing their girl,
Just the cries of barbarian cavalry in the Yan hills.

Ten thousand miles she rode in war,
Crossing passes and mountains as if on a wing.
On the northern air comes the sentry's gong,
Cold light shines on her coat of steel.
The general dead after a hundred battles,
The warriors return after ten years.

They return to see the Son of Heaven,
Who sits in the Hall of Brilliance.
The rolls of merit spin a dozen times,
Rewards in the hundreds and thousands.
The Khan asks her what she desires,
"I've no need for the post of a gentleman official,
I ask for the swiftest horse,
To carry me back to my hometown."

Her parents hearing their girl returns,
Out to the suburbs to welcome her back.
Elder sister hearing her sister returns,
Adjusts her rouge by the doorway.
Little brother hearing his sister returns,
Sharpens his knife for pigs and lamb.
"I open my east chamber door,
And sit on my west chamber bed.
I take off my battle cloak,
And put on my old-time clothes.
I adjust my wispy hair at the window sill,
And apply my bisque makeup by the mirror.
I step out to see my comrades-in-arms,
They are all surprised and astounded:
'We travelled twelve years together,
Yet didn't realise Mula

Yet didn’t realise Mulan was a lady!'”

The buck bounds here and there,
Whilst the doe has narrow eyes.
But when the two rabbits run side by side,
How can you tell the female from the male?

This might be helpful.

I have no idea if they are going to stick with the ballad or they are following one of the later adaptations.

It is probably catered for the Chinese audience but this corona virus epidemic is not going to help this movie.
