Thankfully, my bride-to-be gave up on her dream of spending 10,000 RMB per table and we used a buffet that was a LOT cheaper. That let us pretty much break even on the wedding meal costs, plus or minus 10%.
Keep a watered down bottle with you at the head table - preferably not sitting out where others will use it and realize the game. Keep your baijiu glass filled from it, and be ready to grab it for a quick refill if you see a queue of people forming to toast you. Also, when you approach a table to toast, have your glass pre-filled, but have a friend nearby having your special bottle handy for your refill before the next table. This forces people at the table to top up from the full strength bottle at their table.
Another variant - some brands come in 2 or 3 strength levels. Give the guest tables 55% and make sure yours is only 30% (and still consider watering it down some). Normally, I'd never condone cheating at a drinking game. In this case, it's you against a pile of guests and you'll be under the table far too early if you decide to play fair.
Sadly, I didn't have time to prep a special pre-diluted bottle for my wedding. Happily, I got away with toasting with red wine a few times and then kept sneaking some sprite into a larger glass of baijiu for some of the toasting. I was only two and a half sheets to the wind by the time the lunch ended and we migrated off to the KTV after party.
