From early morning on Hai Thinh beach (Nam Dinh), there were dozens of fishermen leading the sea. This is a job that helps people have the main source of income for the family. The job of the players who don and rake depends on the country. Big countries go a little later, sometimes until after 1pm to end. The tool for scratching is a 5-7 meter long tattoo, the base of the tattoo is attached with a razor neatly in a rectangular iron frame so that it can be inserted deep into the sand and move more easily. Despite the hardship, but for 40 years, Mr. Tuy has not given up a day except when he is sick. Scratching places are usually sandy beaches on the sea with a depth of 0.5-1m above sea level. The person who rakes with one hand holds the bamboo handle, the other hand resting on the waist with a recoil. Average raking is 15-20 meters a time calculated about 10km per session and soak in sea water continuously for 6 hours. If locating, the fishermen have to immerse themselves in the sea water, while for the claw don, they will have to bow down to dig from under the sand layers. Fishermen have to use small shovels to flip up the sand and sea soil to dig. Don is shaped like a bottle but smaller so you have to look closely to see. The don season peaks from May to June Due to direct contact with water and sea soil, the legs and hands of the rake fishermen have many wrinkles and pale skin. The donation bucket accompanies the fishermen every raking session If they are lucky, each day fishermen can earn from 300-500 thousand VND. On days when the weather is not favorable, we can only scratch a little and we have to go home. Don will be cleaned by fishermen for processing and consumption The fresh pawns cost 30-50 thousand VND / kg and are very popular with the people. Since the donation, the donation has a value, the job of rake and donation attracts more people to do and less and less.
