Sydney has its share of oddities, indeed surprising.

Sydney, a city filled with four wonders and three mysteries, is truly astonishing and thought-provoking.

Firstly, it's the remarkable juxtaposition of the azure sky and the blue sea with white clouds.

Sydney seems to be specially favored by the heavens, with its perennially pleasant climate and azure skies adorned with pristine clouds.

Whether it's the gentle light of dawn or the hues of dusk, the sight of seagulls soaring in the sky through the window instills a profound sense of tranquility and comfort.

In contrast, Beijing is often shrouded in smog, making blue skies and white clouds a luxury, a disparity that's truly striking.

Secondly, the sight of kangaroos and koalas casually strolling the streets is truly astounding.

It's common to see kangaroos leisurely hopping around in alleyways while koalas lazily nap in trees.

Such harmonious scenes of nature are simply breathtaking.

The third wonder is the stunning beauty of Sydney's beaches, resembling paradise on earth.

The fine sands, clear waters, and the summer sun make them ideal places for relaxation and recreation.

Playing with children on the beach, feeling the gentle breeze and the rhythm of the waves become cherished experiences.

Lastly, Sydney's exquisite Western cuisine is simply irresistible.

Whether it's delicate French cuisine or hearty American BBQ, the variety and uniqueness of flavors are mouthwatering.

Apart from these four wonders, there are three mysteries that puzzle the mind.

Firstly, why are Sydney-siders so passionate about outdoor sports?

Whether it's a sunny afternoon or a rainy morning, one can always see people jogging in parks, beaches, and mountains.

This spirit of embracing physical activity is both surprising and admirable.

Secondly, how does Sydney's multiculturalism coexist harmoniously?

The city brings together people from all corners of the globe, each bringing their own culture, beliefs, and customs.

However, in Sydney, these differences don't lead to conflicts but rather blend together to form the city's unique charm.

Lastly, why is environmental consciousness so deeply ingrained in Sydney?

Whether it's waste separation, water conservation, or reducing carbon emissions and protecting wildlife, Sydneysiders are diligent in their efforts.

This profound respect and care for the environment are truly admirable.
