Common Misconceptions

"Hong Kong IS China"

Politically yes, practically no. For travelers, they're different destinations requiring different preparation.

"I can use my Hong Kong visa for mainland"

No. Separate immigration systems. Separate visas.

"WeChat/Alipay work the same in both"

They work in both, but mainland setup is more essential. Hong Kong accepts cards; mainland doesn't.

"Everyone in Hong Kong speaks Mandarin"

Cantonese is primary. Mandarin is understood but not preferred by locals. English is often easier.
