Recommend some publishing space, preferably masculine, or ancient poetry, on the battlefield, so that people will think I am a man at first sight?

Of course, I can recommend something that meets your requirements. Here are some possible copywriting:

If life is just like the first time, you don't have to draw a fan in the autumn wind. -Na Lanxingde's Magnolia, Antique Words, Friends of Cambodia

Eat pork when you are hungry, and drink Hun blood when you are thirsty. -Yue Fei's "Man Jiang Hong writes Huai"

Yellow sand wears golden armor in hundreds of battles, but the loulan is not returned. -Wang Changling's "Seven Military Services, the Fourth"

Why didn't the great man take weapons to collect the fifty States of the mountain? -Li He's "Thirteen Poems of South Garden" (5)

The vastness of the wilderness is deeper than trees, and the moon is very close to the moon. -Meng Haoran's "Sleeping in Jiande River"

Waiting for the autumn of the eighth day of the ninth lunar month —— Huang Chao's The Last Happiness.

Hurried through the flowers, lazy to look back; This reason is partly because of the ascetic monk, and partly because of who you used to be. -Yuan Zhen's Five Poems of Self-reflection, No.4.

Looking back, how powerful he was when he led the Northern Expedition and recovered lost ground! -Xin Qiji's "Never Meet Le Jingkou Gubeiting Nostalgia"

Others laugh at me for being crazy, and I laugh at others for not being able to see through it. -Tang Bohu's Song of the Peach Blossom Temple

I hope these ancient poems and sentences on the battlefield can show your masculinity and unique personality.
