Don't let Zhang Hexian's age fool you as the 94-year-old has a particular set of skills that make her a nightmare for thugs anywhere.
The resident of Ninghai County in east China's Zhejiang Province has been practising Chinese martial arts since she was four and through the years she has refined her skills with great diligence and effort to become affectionately known as "Kung Fu Grandma".
Regarded as "the village of martial arts," nearly everyone in the village where Zhang lives practices kung fu.
As the eighth descendant of her family, Zhang learned kung fu under her father's instruction at the age of four and has continued to practice throughout nine decades.
"My dad took me to sleep at that time. When we woke up in the morning, we started practising kung fu in bed. I learned basic martial arts skills such as pushing palm and throwing a punch at an early age," said Zhang Hexian.
Practicing kung fu has become a daily routine in Zhang's life.
Every morning, Zhang does kung fu exercises without feeling tired.
Apparently she is in good health.
"She wakes up very early and does physical exercises every morning. She usually runs around the village for morning exercise,"said Zhang's son Feng Chuanyin.
Zhang recalled that she once fought against a bully when she was young.
The bully was beating his wife when Zhang saw him.
To uphold justice, Zhang grabbed his collar, ripped his shirt off and urged him to behave well.
Apart from being a deterrent to hooligans and ruffians, Zhang is also a warm-hearted woman willing to help others, which is one of the secrets of her longevity.
"She always has a good mood with a positive attitude. Helping others is also good for her health," said Feng.
