"Second-hand¹ fragrance²" is perfume that is so strong that it makes other people around feel uncomfortable. Therefore, it is disliked in public places like second-hand smoke.

"I just can't breathe amid those heavy scents³", said Chen Rong, a customer service representative of a foreign trade company. Her company took part in the 101st China Import and Export Fair, or Canton Fair, in April in southern China's city of Guangzhou.
Chen said during the 10-day event, she had to talk with scores of foreign businessmen everyday. "The heavy perfume they were wearing made me sick!" she complained.

Many feel the same way as Chen. Xu Yi, an advertisement mastermind also from Guangzhou, even compared second-hand fragrance with chemical weapons.

"The other day in the subway, I was almost knocked down by the overwhelming smell," he lashed⁴.

As wearing perfume is becoming a fashion in the southern Metropolis⁵, many people in Guangzhou are calling for a restriction⁶ on the use of heavy fragrances⁷ in public.

Professor Gou Lijun, an etiquette⁸ expert from Jinan University says that wearing perfume is a way to show one's respect for other people, however, overwhelming fragrance will just do the opposite.

And what makes things worse is that the "second-hand fragrance" may actually make people ill. Doctor Zhang Yanan works in the infectious department of a local hospital. Zhang says that there are some people who are allergic⁹ to perfume. They may feel giddy and struggle to breathe if they are subjected to the overwhelming smell for a long time.

In western countries, "second-hand fragrance" has been deemed a source of air pollution for a long time.

The Canadian city of Halifax launched a "no-scent encouragement program" in 1996, urging people not to wear fragrances to help reduce illness and discomfort¹⁰.

In Paris, some big enterprises have enforced bans on the use of heavy perfume during work time.

In Guangzhou local authorities so far have no plans to restrict fragrance use in civic¹¹ areas.
