Deputy Chief Secretary Warner Cheuk said he thinks the streets on Hong Kong Island have improved in cleanliness, after taking a stroll from Shau Kei Wan to Western.

Writing on his social media on Wednesday, Cheuk described his 4.5-hour walk with his colleagues the day before as a "feat."

“Along the way, we conducted inspections to find out if the roads were clean… in total we walked for 21km,” he wrote.

The minister said some of the roads they inspected include Shau Kei Wan Main Street East, King's Road, Causeway Road, Hennessy Road, Queen's Road East, Queensway and Belcher's Street.

He said these roads were generally cleaner than before, as he didn’t see too much in the way of trash, cigarette butts, water or gum stains along the way.

"Here, I would like to especially extend my compliments to colleagues at the Eastern District of the Food and Environmental Hygiene Department," Cheuk said, noting that the roads in the area were very clean and deserved a score of eight out of 10.

He pointed out that the tour on Tuesday was arranged on the day and that what he saw was "the actual hygiene situation" which had a high reference value.

The deputy chief secretary said he plans to inspect Kowloon on Sunday.
