A man in eastern China has sued a gym after he paid it more than 870,000 yuan (US$120,000) for memberships lasting 300 years before the management fled with his cash.

The man, known as Jin, has also sought the help of a television station to expose the Ranyan Gym in Hangzhou, Zhejiang province.

Jin showed the station 26 contracts he signed with the gym for buying memberships and coaching sessions.

“From May 10 to July 9, I bought about 1,200 lessons and membership cards with an accumulative validity period of 300 years, at a total cost of 871,273 yuan,” Jin was quoted as saying.

Jin, who has worked out at this gym for three years, said that on May 9, a sales executive told him that there was a promotion for existing customers.
