Try not to drink tea in the morning to let your stomach rest. If you must, opt for ripe tea and limit it to half a brew (6 cups) or one full brew (12 cups), depending on your constitution and stomach tolerance.
Avoid drinking tea between lunch and 3 PM. Do not drink tea within an hour after meals, and avoid heavy, hard-to-digest meals or carbonated drinks like beer before tea.

From mid-afternoon (3–5 PM), drink one or two types of tea based on your stomach's tolerance, and let your stomach rest before dinner. Afternoon is the best time for tea, but limit new teas to one type—aged teas are preferable.
After dinner, wait at least an hour before drinking tea around 8:30 PM. Choose older teas and avoid strong concentrations, especially with new raw teas. Limit yourself to two brews—either two raw teas or one raw and one ripe. Ripe tea helps curb late-night cravings, as eating after 9 PM is generally unhealthy.

Control your tea portions—stick to "sipping" quantities. Avoid using large teapots (180CC) for one or two people; a 120CC brew is enough for 2–3 people. Don’t overconsume just because the tea is good—it’s not worth upsetting your stomach.
For those with indigestion or mild gastritis, heal first, then adopt light dinners, avoid late-night snacks and alcohol, and eat easily digestible foods before tea. If tea causes discomfort, a couple of soda crackers can help settle your stomach.

Final advice: If you have a strong stomach, lucky you—drink however you like! For those with weaker stomachs, develop gradual habits to improve tolerance. Don’t overdo it—I learned this the hard way by overdrinking new teas. Back in the day, I was all about late-night barbecues and chugging beer. Now, my tea buddies call me "Huang Four Brews"—I stop after four infusions. What a laugh (or cry)!
