Can I fly Langkawi Malaysia to Guangzhou take train to Macau and HK total 10 days without visa

Could you be more detailed? You don’t need visa for Macau and HK, but for Guangzhou, it depends. If you enter Guangzhou by flight, and stay there for 144 hours, and then go to Macau or HK, you can enjoy the 144 hour free transit. In this way, no visa for Guangzhou will be needed either.
