art at Yunnan. The houses are decorated with traditional culture. Admiral Zheng He who set sailed on the 15th of 6th Chinese Calendar month ( Farmer's calendar or Yin Calendar), set sailed at Liu Jia port near Shanghai. We understand that expert can sail west south west by south wind. So they reached Vietnam, then east coast of Malay Peninsula, west of pulau Puteh, north of Batam then made use of stronger south wind to sailed north to Malacca. They had started their voyage in early summer to make use of gentle south wind. If they set sail by August or September of that year...they might have encounter typhoon and at least strong south wind which could prove too strong to handle by late summer. Luck ? science?
