Many scholars disagree about the actual length of the treasure ships. The largest ships in the 130 m range were felt to be unseaworthy and only for display on the Yangtze river. Most scholars think the actual expedition ships for exploring were in the 60-70 m range.

After Zheng He, China basically didn't go further with exploration while European exploration continued basically for another 500 years. It is really not the size of the ships that matter. It is what you do with the ships. I am not sure why you are trying to turn a thread in the tennis tips section into a China versus Europe thing.
