China's ancient capital has long been a draw for snap-happy visitors, but the city's latest charm offensive is also attracting emerging industries.

A grand entrance ceremony takes place at Xi'an's Ming Dynasty (1368-1644) city walls every day, as the ancient capital of China opens its spectacularly preserved South Gate to the masses with great pomp and pageantry, as it would have done for VIPs in the olden days.

Hoards of performers stage a Tang Dynasty-style (618-907) welcome - the period in which the original walls were built - as they lead crowds of tourists armed with cameras through the park, over the bridge and into the city proper.

Unfortunately, when I was last in town, I arrived late to the event and had to watch from afar, clinging onto the park railings as I craned my neck to take in the proceedings, like a peasant of times past stretching for a glimpse of those lucky enough - or in this case punctual enough - to be treated to such an honorable reception.

But, my hapless position on the sidelines provided me with a glimpse of the radical change of the times that today everyone is welcomed and celebrated, especially in the last 40 years of opening-up.

Xi'an, a "natural museum" that served as China's capital for 1,100 years and is home to the world-renowned Terracotta Warriors, is already known as a "world-famous destination for traveling", according to the local tourism board's deputy head, Kang Lifeng. But there is still significant work underway to further open up the city to the world.

Xi'an has long been a leader in this regard, and, as Kang says, it was one of the first cities on the Chinese mainland to open its gates to international visitors. Ongoing initiatives include improving English-language signage, making the city's visa-free policy more competitive and easier to use, as well as organizing foreigner-focused activities that draw on and combine Western and Eastern cultural elements.

On this, my third trip to Xi'an, I noticed many new features since my last visit two years ago.

The city is more alive at night than ever, thanks to the bright lights that keep the shops and streets open until the early hours and illuminate the city's many architectural wonders.

As I wandered through the Muslim quarter that lies alongside the 600-year-old Drum Tower, the vast diversity of cuisine and culture was essentially floodlit, helping locals and visitors alike to navigate along the bustling alleyways and the vendors to achieve a roaring trade.
