There's an easier way (at least IMO)....
1. Say "Tsin". Notice how you make the sound "ts" with your tongue and teeth.
2. SLIGHTLY increase the gap between your upper and lower teeth.
3. Say "Tsin" with the modifications in Step 2.
Alright, back to topic. One thing I've been thinking about these days is whether China's UA really has as much impact as we initially thought - that's with the latest information we got stating that their bonus to Eurekas is +10%. I have a feeling that if Eurekas are really that great, then every civ will be committed to the search for them in early game - making China's +10% not as useful, at least on paper. There might be scenarios where the boost is rendered kinda obsolete.
An abstract example: an "empty" 100 bulb tech, your science output is 25/turn. Chinese Eureka boosts it to 60/100, but you still need 2 turns to complete the tech - just like any other civ that got the same Eureka. Sure, the extra 10 bulbs will most likely be carried over to the other tech in your beeline (or WILL they?), but you might be facing the same issue there as well.
