I'm living in Chengdu and I'm currently looking for a tour that can work with limited budget.

I have yet to see the pandas (I'm interested in the prices of either volunteering or taking a photo with a panda), I also would like to see the giant Buddha in Leshan, the monkeys in Mt. Emei, Jiuzhaigou, find an affordable cruise around the Yagtze river, visit Xi'an and arrive in Beijing. I am aware that to visit all of this places might be costly, so I would like some advice on which routes might be best for me. I would rather stay in a hostel than a fancy hotel as it is also cheaper. I could start before the 30th of June (maybe around the 20th) or just on the 30th of June and arrive in Beijing at least by the 9th of July.
