What made wu chao unique in ancient China?

What is a good theme/thesis to write about when comparing the two short poems: Lost Sister and Turtle Soup?

• I am looking to write a comparative paper about the two and was looking for a thesis that would help jump start my 6-7 page paper. Any help would be appreciated. Thank You. Cathy Song "Lost Sister" 1 In China, even the peasants named their first daughters Jade― the stone that in the far fields could moisten the dry season, could make men move mountains for the healing green of the inner hills glistening like slices of winter melon. And the daughters were grateful: They never left home. To move freely was a luxury stolen from them at birth. Instead, they gathered patience; learning to walk in shoes the size of teacups, without breaking― the arc of their movements as dormant as the rooted willow, as redundant as the farmyard hens. But they traveled far in surviving, learning to stretch the family rice, to quiet the demons, the noisy stomachs. 2 There is a sister across the ocean, who relinquished her name, diluting jade green with the blue of the Pacific. Rising with a tide of locusts, she swarmed with others to inundate another shore. In America, there are many roads and women can stride along with men. But in another wilderness, the possibilities, the loneliness, can strangulate like jungle vines. The meager provisions and sentiments of once belonging― fermented roots, Mah-Jong tiles and firecrackers―set but a flimsy household in a forest of nightless cities. A giant snake rattles above, spewing black clouds into your kitchen. Dough-faced landlords slip in and out of your keyholes, making claims you don't understand, tapping into your communication systems of laundry lines and restaurant chains. You find you need China: your one fragile identification, a jade link handcuffed to your wrist. You remember your mother who walked for centuries, footless― and like her, you have left no footprints, but only because there is an ocean in between, the unremitting space of your rebellion. Turtle Soup You go home one evening tired from work, and your mother boils you turtle soup. Twelve hours hunched over the hearth (who knows what else is in that cauldron). You say, "Ma, you've poached the symbol of long life; that turtle lived four thousand years, swam the Wet, up the Yellow, over the Yangtze. Witnessed the Bronze Age, the High Tang, grazed on splendid sericulture." (So, she boils the life out of him.) "All our ancestors have been fools. Remember Uncle Wu who rode ten thousand miles to kill a famous Manchu and ended up with his head on a pole? Eat, child, its liver will make you strong." "Sometimes you're the life, sometimes the sacrifice." Her sobbing is inconsolable. So, you spread that gentle napkin over your lap in decorous Pasadena. Baby, some high priestess has got it wrong. The golden decal on the green underbelly says "Made in Hong Kong." Is there nothing left but the shell and humanity's strange inscriptions, the songs, the rites, the oracles?

• Answer:

  Try to read an in-depth analysis on both poems, in something like SparkNotes, or eNotes. Both should point out key elements in the poems, which should [hopefully] help you to begin. Good Luck!
