Si Ji Chun vs Qing Xin
The cheapest way to imitate high-mountain character and the plant that actually produces it. Si Ji Chun flushes almost year-round at low elevation and carries a strong lilac aroma; that aroma is regularly sold as altitude.

What is being compared
Why these get confused
A cheap oolong that smells wonderful and thins out by the third steep is usually Si Ji Chun, and it is a perfectly good tea sold under the wrong description.
Point by point
| Aspect | Si Ji Chun | Qing Xin |
|---|---|---|
| Flushing pattern | Almost year-round, which is where the name comes from. | Two to a few harvests a year at altitude. |
| Elevation planted | Low, in volume — Mingjian above all. | High, where the economics of a low-yielding plant work. |
| Aroma | Strong and lilac-like at low elevation. | Gardenia, with a marked cooling finish. |
| Body | Thinner, with a shorter finish. | Thick, and the reason for the price. |
| Where it ends up | Most inexpensive Taiwanese oolong, and a great deal of bubble-tea base. | Named high-mountain oolong. |
| How to tell them apart | Judge the finish rather than the nose; aroma is what Si Ji Chun does best. | Sustains many infusions with body intact, which lowland tea does not. |
The short answer
Elevation and cultivar are different things, and this pair is where they are most often conflated on purpose. Any high-mountain claim is worth testing on the fourth infusion rather than on the dry leaf.
