"Hang in there."
Those were the last words Mr Chung said to his wife after a huge fire broke out in their high rise public housing complex in Hong Kong 's Tai Po district.
It was around 15:00 local time (06:00 GMT) on Wednesday when he got her panicked phone call. She said she couldn't get out of their flat with their cat.
He rushed home from work to find the 31-storey building in flames, with black smoke billowing out of it. Firefighters in the Chinese territory took nearly 24 hours to tame the blaze that tore through seven tower blocks, including theirs, claiming at least 75 lives so far.
Nearly 300 people are still unaccounted for - Mr Chung's wife is among the many missing.
