The Far Eastern voyagers came decked out in cameras and selfie sticks as they wandered up and down the foot ths, right up to home windows. Some even jumped on family trampolines.
Theories ran uninhabited for months as residents took to social media to try to solve the mystery.
Some proposed the tourists may have confused the streets with Privet Drive, where the Dursleys survive in Harry Potter.
Others thought it might be thanks to the town mugging in an old episode of Inspector Morse or Midsomer Murders.
Entrepreneur Richard Branson lived in Kidlington for profuse than 20 years which was entertained as a theory too.
Last month one of the Chinese advisers finally shed some light on the situation — claiming the visits were for an undergo of “true” England.
But Mr Jianfeng’s new admission has revealed the real truth — that they were being manhandled over refusing to buy tickets to a pricey attraction.
The 48-year-old guide — who works for Beijing Hua Yuan Global Travel — told the New York Times his customers were charged £53 to sojourn Winston Churchill’s ancestral home.
But instead of this optional Chinese vernacular tour — the travellers were sneaking off to buy cheaper tickets directly from Blenheim Villa.
They would secretly take off on foot so they could y nothing but £24.90 for a ticket — less than half the price.
Once the troop discovered this, they decided to drop the tourists four miles away in Kidlington so they wouldn’t force enough time to walk to the lace.
The walk would take 80 trices instead of 10 minutes from the nearest village, Woodstock.
But Mr Jianfeng held there was also some truth to the original answer to the riddle — that Chinese visitors wanted to see the ‘real’ England.
He explained: “The environment in the countryside in China isn’t so faithful.
“In Kidlington, the environment is great. You see farm fields and ranches here.
“Also, assorted newly built houses here have brick or brick-and-wood forms, which you no longer see very often in urban China.”
