What classes of tea are appropriate for Kung Fu Cha?

Oolong class . Kung Fu Cha uses YiXing teapots (more info on YiXing teapots) that retain a high temperature during brewing. High temperature is what it takes to extract flavor from Oolong. 

However, tender tea classes like green tea should NOT be brewed with Kung Fu Cha.

Procedures are dead. What do we look for in Kung Fu Cha?

We look for the right combination of amount of tea leave, water temperature, brewing time, etc. to make a good cup of tea. And keep in mind that Kung Fu Cha offers an advantage over other brewing - higher water temperature.

The procedure illustrated in the coming up pages are just basic steps. Feel free to modify the steps (e.g. putting the YiXing teapot in a hot water bath to slow down heat loss, etc., etc.) if such steps give you a better cup of tea .

1. YiXing teapot (must) - YiXing teapot is slow in losing heat. Small (personal preference is below 6 oz) and deep teapot is preferable for best result.  For convenience, bigger teapots can be used (the trade off is a lesser degree of control over flavor). 
2. Teacups (must) - that is, if you don't want to drink direct from the teapot. 3-4 cups of about 1 oz each is fine, depending on the size of the teapot.
3. Tea Tray (not a must) - quite a bit of spill and waste water is produced during the process. The tea tray holds such water so you don't have to wipe it off the table. It might seem to be just for convenience but it's BIG convenience.
4. Tea Tools (optional) - in the tool set, there are tea shuffle, funnel, tongs, digger, tea needle. You won't get into much trouble though if you brew without the tool set.
5. Tea (must) -  need no expert to tell tea is a must.
6. Faircup (optional) - transitional container when teacups are full but tea in teapot has to be emptied to avoid overbrewing.
7. Strainer (optional) - screens out small pieces of tea leaves.
8. A pair of hands (must), and perhaps your mouth too.
9. Source of hot water (must) - Sorry, please don't try to look it up in the PIC above because it's not there. You can use a variety of source, say, a pot heated on stove, an electronic heating pot, etc. Just make sure whatever you use can give you boiling water.
