And for those who book early, before May 31, 2012, a further $250 per person will be slashed off the price of two of the money-saving deals.
"We want everyone to share our Silver Anniversary excitement by saving on the next tour," said Helen Wong, who founded Helen Wong's Tours in Australia in 1987.
"It's a significant year for us," she said, "so there's no reason why travellers can't benefit and cash in on a sale as crazy as this one.
"Prices on two of the tours - Beijing Bonanza and Shanghai Surprise - are the same as similar tours seven years ago."
The four packaged itineraries in the aptly billed "Helen's Crazy Birthday Sale" promotion are as follow (prices include return flights from Sydney, Melbourne, Brisbane and Perth):
Seven-day Beijing Bonanza, priced from $1590pp, twin share (Brisbane and Perth passengers have extra day at no additional cost);
- Seven-day Shanghai Surprise, priced from $1590pp, twin share;
- 14-day 25th Anniversary Tour of China, priced from $2950pp, twin share;
- 13-day 25th Anniversary Tour of Vietnam, priced from $2950pp, twin share (from $3280pp, twin share from Brisbane and Perth)
"That's $500 a couple," stressed Ms Wong whose company last year passed the 200,000 milestone mark for numbers of Australians to Shanghai.
Helen Wong's Tours' 25th Anniversary Tour to China begins with a flight to Shanghai and covers the sights and sounds of canal city Suzhou, ancient Wuzhen, Hangzhou, Xian (home of the Terracotta Warriors) and capital Beijing.
The 25th Anniversary Tour to Vietnam begins with a flight to capital Hanoi and covers Hoa Lu, Vietnam's first capital, breathtaking Halong Bay, ancient Hoi An, the religious centre of My Son, Hue, Ho Chi Minh City (Saigon) and Cai Be in the Mekong Delta.
All four special tour prices apply to travel in July and August, 2012.
