There is a river in Hebei, Henan, which is loyal to your duty and sincerity. Send: What is the Chinese zodiac sign after the four-character code followed by seven tails?
The answer to this riddle is "horse". "A River in Henan and Hebei" refers to the Yellow River, and the homonym of "professional value" in "Be loyal to your duties and treat the victims sincerely" is "Ma Gui", so it can be inferred that the answer is related to horses. "Four" in "four characters with eight tails" refers to four Xiao's and "seven" refers to seven digits. Combine four characters and seven numbers to get "Ji You Dinghai Wu Jia", in which "noon" belongs to the zodiac of the Year of the Horse. Based on the above inference, it can be determined that the answer to this riddle is "horse".
