Groups of people gathered on Saturday in a park near the fire-ravaged apartment complex to leave flowers and messages in memory of the victims.
Around the block, people also queued to write in the books of condolence placed in special memorial rooms.
"I can't do anything. I can only hope they rest in peace," a 52-year-old man told AFP.
So far, 128 people have been confirmed dead after the fire in the Wang Fuk Court high-rise complex. Around 200 are missing and many are injured, eleven of them life-threatening.
The buildings were under renovation and the fire spread quickly along the bamboo scaffolding that covered the facades. A total of eleven people have been arrested on suspicion of various crimes following the fire.
