A slogan to remind residents to flush the toilet reads "After you finish answering nature's call, please 'Wash, brush and brush!'"
The words "Wash, brush and brush" are from the lyrics of a popular song "Xi Shua Shua." The Chinese words "xi" and "shua" respectively have the same meaning as "wash" and "brush."
To remind people to take care of trees, another slogan reads "A tree cherishes its bark just as a woman cherishes her face. Leave no mark on the bark."
Su Yao, a Beijing resident living in Chaoyang district, said she thinks the new slogans are more impressive and interesting than previous signs.
"The old ones are more serious," she said.
"As far as I remember, there was 'Don't step on me' on the grass in the parks, 'You are obliged to save any drip of water,' and 'Civilized Chaoyang [district]' along Chaoyang Lu in the past," said Su.
