May 22 (Reuters) - PDD Holdings beat first-quarter revenue estimates on Wednesday, powered by strong adoption of its international shopping site, Temu, and as Chinese domestic discount e-commerce platform Pinduoduo attracted more price-conscious customers.

The company's revenue was at 86.81 billion yuan ($11.99 billion) in the first quarter, compared with analysts' average estimate of 75.66 billion yuan, according to LSEG data.
