Parents bid sad goodbye to firefighters

On the side of the mourning wall hangs a board listing the names of firefighters missing since the Tianjin blast with a sentence that reads: "We are here waiting for you to come back."

While the blast has claimed 114 lives, 57 were still missing as of Tuesday.

Zhou Ti, 19, became the first survivor found in the blast center by the rescue team about 30 hours after the accident. A week after the explosion, people still expect more such good news.
