Yuan Yuan's grief for her only brother is tinged with anger.
Seventeen-year-old Yuan Hai was the youngest of 50 firefighters killed in the deadly blasts that hit China's port city of Tianjin on August 12. Of the 57 people still missing, 52 are firefighters.
Her posts on Chinese social media after she learned of his death have wrenched millions of hearts.
"Why were you so heartless to leave our dad and mom for me to take care of?" she wrote on a widely shared post on Weibo, China's equivalent to Twitter.
"We didn't expect you to accomplish great things; we only wanted you safe; we wanted you back, we wanted you back. It's too cruel for dad and mom to see you die before them."
Tuesday is the seventh day since the massive explosions, according to tradition a key time to mourn the dead, and thousands in the city took part in memorials.
The nation has revered the firefighters dispatched to the apocalyptic scene as heroes.
But critics say that the focus on eulogizing them obscures the fact that China's firefighters are poorly equipped and inadequately trained, especially young contractors, who don't enjoy the same military status or pension benefits as staff firefighters.
