It was a triple treat for Global Business Journalism students from Tsinghua University at Bloomberg News's Beijing office.

For the first time in GBJ's 10-year history, the three top Bloomberg News managers in China spoke to students during a single session. Executive Editor John Liu, Beijing Bureau Chief Ken Wills and Shanghai Bureau Chief Charlie Zhu each shared their career experiences and advice with almost 40 master's degree candidates. In a training lab filled with iconic "Bloomberg Terminals," students also heard from a career coach, a data specialist and healthcare reporter Li Hui.

Liu, who oversees about 250 journalists across mainland China, Hong Kong and Taiwan, told the students about Bloomberg success stories and urged them to work their way up in the media business. Use good news judgment, ask the right questions and be willing to accept assignments that "may not be very nice at first," said Liu. He cited the example of a "now very, very powerful" colleague in New York whose first job was to stand over a fax machine and deliver papers around the newsroom. Liu's noted that his own first job in China was with a Russian news agency.

Li Hui, who joined Bloomberg three years ago, underscored Liu's advice. She carved out healthcare as her niche while working as a news assistant at Thomson Reuters because, at the time, it was "an abandoned beat."

"Opportunities come to those who don't hesitate to challenge themselves," she said. "Tag along with a colleague and see how they do things."

GBJ now has more than 230 alumni from China and more than 60 other countries. Visits to Bloomberg's Beijing office have been a tradition for lectures and special events. Alumni work at Chinese media including CCTV, People's Daily, Xinhua, China Daily and Caixin, as well as in banks, brokerages and the government. Others are are at organizations ranging from IBM and to Goodwill Industries, while three graduates are now at Bloomberg News.
