You just need to apply for double-entry tourist visa (L)to Mainland China, Malaysia passport holders don't need a visa to Hong Kong or Macau for up to 30 days, so you just need a tourist visa (L) to Mainland China, is your real itinerary LCCT, Malaysia-Guangzhou-HK-Macau-HK-Guangzhou-LCCT, Malaysia? You enter Mainland China twice.

Dear, Mrs.Linda(Malaysia)
TQ for your reply. Yes, my itinerary are LCCT,MY - GUANGZHOU - HK - MACAU - HK - GUANGZHOU - LCCT, MY from 18/10/10 - 25/10/10. I do know that HK immigration and MACAU immigration have granted 90 days and 30 days Visa Free Privileges to Malaysian Passport Holders but because of I will be travelling by land and by sea from GUANGZHOU - HK - MACAU - HK - GUANGZHOU, which type of visa do I have to apply ?
1)China Tourist Visa (L)
2)China Transit Visa (G)

Please anyone help me out. TQ

Ms.Kok, you can apply for China Tourist Visa (L). If you apply for transit visa, you should have the flight tickets from Malaysia - Guangzhou - HK/Macau -Guangzhou - Malaysia, however, you travel by land and by sea from Guangzhou - HK - Macau - HK -Guangzhou.
