PeacockBass;481899; said:Chinese were elite sailors to my knowledge, correct? If this is the case, I have no doubts they may have landed.
If I remember the documentary right, they speculated that the Chinese had the advantage over a lot of the sailors worldwide due to the invention of the compass. I don't think the Chinese had spread the use of the compass to other lands during this time and since they are the only ones had access to it, navigating the seas would have been easier.
Wikipedia says compass was invented over 1700 years ago.
