I just sent a packaget to somewhere closed to Wuhan using UPS, it took three business days. If you mail out today, they should get it next Wednesday. Call UPS 800 number and ask for "Global saving". It is flat rate, for anything below 1 lbs the rate would be about $50, give or take. If you are going to just send a couple of piece of papers (such as DS-156 forms), it will be cheaper just use USPS.
