Why is there a big worker chicken playing next to the corpse?

NHK: In traditional folk beliefs...the rooster can pull the sun...has the divinity to ward off evil spirits and reach the sky...the rooster's crow also complements each other with the dawn...brightness... .So...in folk red and white things...to exorcise evil spirits...divination...chickens also play a very important role...in addition to the folk rituals...killing chickens to reward the gods ...In ancient times...raw chickens were also used to replace the dead...but...the most special thing...is that you mentioned using roosters to ward off evil spirits and summon spirits...in traditional funeral ceremonies. ..I heard that it comes from Maoshan Shu...live roosters are often used...for example...when transporting coffins across a river...or to guide souls on the road...live chickens are needed...the so-called soul inducing... Going on the road... means that after the rooster performs the soul-calling ritual... the soul of the deceased can possess it... lead the deceased... to the paradise world... and will not become a lonely ghost... and be possessed. The "soul-calling chicken" with the undead... will be released... and will not be slaughtered and eaten... Furthermore... the rooster will crow... If you encounter Tianxiao... the rooster's crow can also indicate the fate of the ancestors. The undead...find a place...dodge once...and when carrying the coffin across the river...the use of a rooster...is due to the fact that after the death of the ancestors...if they need to return to their hometown for burial...will The coffin containing the corpse... is transported back to the hometown... the journey may be very long... and it is said that ghosts... dare not cross the river... so... when the coffin is transported across the river or bridge... .It is necessary to tie a big rooster to the coffin...The filial son must shout loudly...and beat the rooster with a stick...to make it crow...In this way, the souls of the ancestors can be removed..." Call across the river"...So...this rooster is also called...the soul-attracting chicken...but...not all chickens used to attract souls...are all live roosters. ..Manchu folk paper-cutting...there are the so-called "soul-inducing chicken" and "chicken crowing pillow"...the former is a chicken-shaped paper-cut...used to be pasted inside the coffin...the latter is made of yellow paper Make it into a triangular shape... then use red paper... cut out the chicken head and tail... stick it on the triangular shape... and then put it under the pillow of the ancestor... as a burial object... this way It can lead the leaders...to the paradise world...and in the ancient funeral customs in the Jiangnan area...the birthday pillow was embroidered with the image of "a boy lighting up the lantern and a golden rooster leading the way"...it also has the same meaning... .In the old funeral customs in South China...according to Kanyuology...there is also the so-called "chicken jumping into the well" ceremony...the well...refers to the tomb where the coffin is placed...coffin... Before being buried...a filial son must first prepare a rooster...let the Feng Shui master pick it up...then stand in the tomb...recite a mantra...then bite the rooster's comb...and drip the chicken's blood in the tomb. ...drop the drops in 5 directions in the southeast, northwest, and northwest...then recite the incantation...throw the chicken out...let the rooster jump out of the grave...this is called "covering the evil"...if you do this... .I heard that all the evil spirits in the tomb can be dispelled...or be "carried away" by the rooster...to avoid this tomb...dead corpses from happening in the future...
