"However, there always exists food that has not been discovered, hiding in the hills and valleys, rivers and seas and deserts and grasslands in China." "These are the realms of secrets that we want to explore." "During early winter in Dalai Nur, Inner Mongolia, the temperature has dropped to minus 30 degrees Celsius." "Bring the tools here." "Today's operation is crucial, and it starts with breaking the ice in the center of the lake." "Dalai Nur' in Mongolian means 'a lake that is like the sea'." "Come on!"

"The gulls have waited long to enjoy a feast." "Huazi fish can refill their energy to complete the migration to Siberia."

"This is a competition in which only the fittest can survive." "Only the strongest fish can make their way to the spawning ground." "Huazi fish are within easy reach, but the fishermen will not catch them in this season." "In the night when predators are gone," "Huazi fish are speeding up."

"The sodium ions in the sauce can activate the salt-free mutton." "The sulfur compounds will cause slight neural burning sensation in the mouth, making the meat taste even better." "Meanwhile, the sauce also produces natural vitamins that can aid the digestion of meat."
