However, just several hours after being appointed, he submitted his resignation letter to local authorities, explaining that he did not have professional qualifications for the job.

Recently, he sold his mobile phone and watch worth a total VND2 billion (USD86,956) which he is going to spend on buying house in District 5 for around 20 homeless people.

"I have not yet found any house which is appropriate. Each person will be given an instant noodle packet every evening. When they die, I will hold a funeral for them."

During the 25-year working process in District 1, he never turned down any challenging jobs. He voluntarily proposed for being allowed to work in the most remote district of Can Gio but was refused.

He was highly appreciated to be brave and determined in the pavement violation crackdown by the city authorities as well as the public.
