If hit with on-trip surprise charges, how to complain in Luoyang?

[Direct conclusion] 【On-trip surprise charges outside contract are violations: you may refuse and complain. Key points to keep in mind: 1. First on-site clearly tell the tour leader 'not in contract, refuse payment', simultaneously contact the booking agency () to stop it; if still forced, complain to 12345/culture-tourism, keeping evidence.】 Steps: Four prevention actions: ◆ Contract lists 'exclusions with reference prices': show potential extras upfront. 2. ◆ Refuse vague charges: 'comprehensive fee'/'local tip' without contract basis, don't pay. 3. ◆ No cash to guide privately: all fees via contract and corporate account. 4. ◆ Read itinerary before departure: know what's included daily.
