• Have we altered the outcome?
Have we altered the outcome?
• Sichuan Red Cross personnel desperately in need of relief when we arrived
• Victims with minor injuries were basically ignored: had we not been there
• Symbol of warmth and care from Hong Kong
• We should have been there one day earlier
Our efforts will be felt in the future
• The scale is large
• The nation is capable
• But Hong Kong is part of the nation
• Chengdu could be doing well
• But how about Mianyang, Mianzhu and all affected places at county level?
• How about Guiyang? Gansu?
Our efforts in the future
• Social rehabilitation
• Rebuilding of hospitals
• Mainly at county level, where the local resources are not adequate
Next phase of help
