Travel Ceramic Tea Set,Sandalwood Handle Teacups Set,with Tea Caddy and Portable Tea Bag

Since there is no sharing pitcher, how do you avoid oversteeping the remaining tea while you drink the first cup?

Can you heat this pot up on the stove? Or do you have to put warm water in it?

Xianchen or yanqi Looks like the same color what is the difference?

I bought this travel tea set, can I order another two extra same tea cups?
