Chandni Chowk To China Yts likely refers to the 2009 Bollywood action-comedy film starring Akshay Kumar and Deepika Padukone, specifically in the context of the popular torrent site YTS (YIFY)
This was the first Indian film allowed to shoot on the Great Wall of China . The crew had a strict seven-day window to complete the action sequences, forcing Akshay Kumar to work 18-hour shifts in freezing conditions.
If none of these work, you may understand why the YTS search term persists.
