Penghu's culture bureau is moving to fine a tourist who climbed the arch of the island's landmark cross-sea bridge and posted video of the stunt online — bad news for the climber, who taunted critics not to report them.

• A tourist climbed the arch of the Penghu Cross-Sea Bridge and shared footage on Threads, telling would-be critics to stay away.
• The culture bureau says it will fine the person under Taiwan's cultural heritage law.
• Penalties for damaging a historic structure or its fittings run from NT$300,000 to NT$2 million.
• Officials say the stunt risked both damage to the bridge and the safety of the climber and other visitors.
• The bridge is a major tourist draw and a protected piece of local history, so damage to it may be impossible to undo.

Outlook: Expect the fine to proceed and tighter warnings against climbing at the site during the busy travel season.
