Fang Li's older sister, four years her senior. She is caring and responsible, noticing Fang Li's movements first and eagerly feeding her water from a precious pouch. She reluctantly limits Fang Li's water intake because it may be all they have for days. She licks water from her hands to avoid waste. She watches longingly at the half-biscuit but says nothing, prioritizing her injured sister's needs. She is sensible and enduring despite her young age.
