What are the "taboos" of sailing?

In daily life, people like the word "eight", which is homophonic with "hair". It is widely rumored that people can get rich with the word "eight" But the fishermen in Haishan are most afraid of "eight" and eight people in production. They choose one day to start shipbuilding and new ships to go to sea. They don't choose the 8th, 18th or 28th. There is a reason why seamount fishermen taboo the word "eight". The legendary "Eight Immortals" are all shipwrecked survivors. Shipwreck is the most painful thing for fishermen, so it is taboo. If there are eight children on board, it is like "eight immortals crossing the sea", each showing his magical powers and holding his own opinions, which delays production. "There are no fish in the sea, and the rice jar is empty." On the eighth day of August every year, there are often strong winds and heavy rains, and the sea is rough, so fishermen can't go out to sea to produce. Fishermen call it "eight immortals crossing the sea, not making money." 1945 The typhoon hit hard on the eighth day of the eighth lunar month, and the century-old giant banyan was uprooted. The ship in Changxitou was carried to the top of the mountain, and the ship in Haishan suffered heavy losses. The masses call it "the waves". On August 18 and 28 of the following year, there was another hurricane and rainstorm. Repeated natural disasters have brought disasters to fishermen, so fishermen in Haishan are most taboo about "Eight".
