HONG KONG, May 14 (Reuters) - China's Tencent Holdings posted a 6% rise in first-quarter revenue on Tuesday, beating analyst expectations, as business services and advertising sales deliver strong revenue growth.

The world's largest video game company and operator of the WeChat messaging platform said revenue reached 159.5 billion yuan ($22.04 billion) for the three months ended March 31.

That compared with the 158.44 billion yuan average of 19 analyst estimates compiled by LSEG. ($1 = 7.2378 Chinese yuan) (Reporting by Josh Ye; Editing by Jacqueline Wong)
