Liu and Liu are really brothers. Liu is four years older than Liu Xiao. He was Liu's teammate when he was an athlete. Later, after Liu became a coach, he also coached Liu.

"Pillar" has a special meaning. Both Liu and Liu are table tennis players, but Liu's career is not as smooth as Liu's. When Liu has become the main force of the national team, his younger brother Liu is still struggling in the provincial team, which also makes Liu change his mind. He hopes to fully support Liu.

Liu and his brothers are not related by blood, but their names are only one word apart. What impressed China fans most about Liu was his "thrilling" match with Korean players at 200 1. Liu saved seven match points in a row and finally won, also known as the hero to resist US aggression and aid Korea.
