Part of the lyrics: On this Halloween, the legendary dance ceremony, the old count duck proposed to the swan. It is never wrong to marry me. There are many fertile farmland. On this Halloween, it is said that the fireworks will not go out and the performance will not stop. Please show me your admission ticket, two sweets for a mask, trick or treat.
