Input: Consider Input: Context: Modeled after US hot website.com, group buying websites are now popular in China. These websites use the power of group buying to get competitive discounts for a daily deal on some best stuff to do, see, eat and buy in the cities across China. Discounts are available within just one click. Zhao lei, a software engineer in Beijing, loves the one-hour lunch break at noon,as it is the best time for him to check "today's special" at his favorite group buying websites . Sometimes he searches for great deals at directory sites devoted to the new shopping space. Zhao spends around 800 yuan($117.65) on group buying every month, mostly to buy food coupons for eating at some nice restaurants and occasionally to find something fun to do. " I love group buying. In addition to the competitive discounts it offers, it helps me get something fun, exciting and new, and such surprises give me a reason to try something new," he said. When he finds a really good bargain, he will send the link to friends or colleagues through MSN,QQ, or e-mail, or share the information at some social networking websites. In doing so, he often gets a certain cut off the price. At some sites, buyers are invited to leave notes about what they want to buy and the website will consider it if similar applications reach a certain number. That is how Zuo got her digital camera after waiting for two months. "It is cool. I want to buy a new digitgal camera for my trip to Switzerland this winter, but I never expected such cheap prices!" Zuo said.

Input: Consider Input: Context: In 1740, the Mon of Lower Burma revolted against the Toungoo Dynasty and founded the Restored Hanthawaddy Kingdom based in Pegu . Throughout the 1740s, the Hanthawaddy forces were winning against Upper Burma-based Toungoo armies. The Siamese were concerned by another rising power in Burma since a strong Burma historically meant future invasions to Siam. Concerned, the Siamese court readily gave protection to the Burmese governors of Martaban and Tavoy who had fled to Siam. In 1745, they sent a diplomatic mission to Ava to evaluate the political situation there, and were received by the Burmese king Mahadhammaraza Dipadi. They saw an Ava court that was on its last legs. By 1751, Restored Hanthawaddy forces were closing in on Ava. The Siamese concerns about the emergence of another strong dynasty based in Pegu appeared imminent. Perhaps as a precautionary measure, the Siamese decided to move their forward base into the upper coast in 1751. While it remains unclear as to whether the Siamese ever intended to go beyond the coast into mainland Lower Burma, the Siamese action nonetheless rang alarm bells in Pegu. Deeply concerned, the Hanthawaddy leadership withdrew two-thirds of their army back down to Lower Burma immediately after they had toppled the last Toungoo king in April 1752. This redeployment of Hanthawaddy troops proved a critical turning point in Burmese history as it gave nascent Upper Burmese resistance groups much needed breathing room. The Hanthawaddy command left less than 10,000 men to pacify all of Upper Burma. Taking advantage of light Hanthawaddy troops, one resistance group, the Konbaung Dynasty led by Alaungpaya, drove out Hanthawaddy troops from Upper Burma by May 1754. Konbaung armies invaded Lower Burma in 1755, and captured Pegu in 1757, ending the 17-year-old Mon kingdom. 
 Question: Who sent a diplomatic mission to Ava in 1745?
