At the 2010 Asian Indoor Athletics Championships, she won her first senior medal as she came runner-up in the shot put to Iranian Leila Rajabi. However, she was not in as good form outdoors and was beaten to the title at the 2010 World Junior Championships by the less experienced Geisa Arcanjo. The 2011 outdoor season proved to be a breakthrough year for Meng and she began with a throw of 18.09 m on the Chinese Athletics Grand Prix circuit – her first clearance over 18 metres. She improved her best further at the 2011 Asian Athletics Championships, tossing the shot to 18.31 m and defeating fellow Chinese thrower Liu Xiangrong to win the gold medal.
